Redraw this illustration while preserving the overall composition, character placement, interaction, scene layout, dramatic intent, and camera framing as closely as possible.
Use the second reference image as an expression and scene-context reference, especially for the left character’s frustrated, slightly exasperated, mildly incredulous mood.
Use the third reference image as a skin tone and skin-rendering reference, especially for the soft luminous complexion, smooth texture, gentle blush, and delicate anime-style skin shading.
Use the additional reference image of the pink-haired ghostly noblewoman as a reference for the right character’s facial design, warm illumination, skin rendering, and treatment of the surrounding ghostly wisps only, while preserving the original scene, pose, costume identity, character placement, and overall composition.
Use the small cropped reference of the left character’s original expression and torso area as an additional guide for her intended mood and general pose energy, but prioritize anatomical coherence and correct body orientation over accidental distortions in the problematic version.
Redraw this illustration as a polished early-to-mid-1990s Japanese fantasy RPG key illustration, reflecting the elegant visual language of Japanese fantasy strategy games, anime illustration books, and romantic shōjo-fantasy artwork from approximately 1991–1995.
The final image should combine the dramatic clarity, heroic presence, and refined fantasy atmosphere of early-1990s Japanese RPG promotional art with the graceful silhouettes, romantic colour harmony, jewel-like eyes, decorative costume design, and gentle fantasy elegance associated with period shōjo-oriented anime illustration.
Use delicate but confident linework, softly modelled cel shading, warm luminous skin tones, flowing hair with carefully separated locks, richly described fabrics, refined accessories, and a detailed atmospheric background.
Preserve the overall composition, dramatic storytelling, relative character placement, colour scheme, costume identities, signature accessories, and background concept while significantly refining the anatomy, facial expressions, line quality, costume construction, lighting, shading, and overall rendering quality.
Set the scene in a mystical Japanese ghostly mansion garden, featuring stone stairways, traditional architecture, drifting cherry blossoms, soft mist, and a dreamy supernatural atmosphere.

Aya Shameimaru, Megumu Iizunamaru & Hatate — Original Blogger Post
Redraw and refine the supplied illustration as a highly polished contemporary Japanese anime illustration with luminous, richly rendered colouring, delicate linework, soft dimensional shading, and an exceptionally refined digital-painting finish.
Use the attached image as the main visual basis and preserve its:
overall mountain-stream setting
three-character arrangement
left-to-right storytelling
pose relationships
facial expressions
colour atmosphere
water rendering
lighting direction
dynamic energy
humorous mood
camera distance
approximate character scale
overall spatial staging
Keep the image as close as possible to the attached version while correcting the remaining anatomical and design issues described below.
Render all three figures clearly as adult winged mountain-spirit women with mature proportions and a clean, polished contemporary anime finish.
Their designs should remain originalised folklore-inspired fantasy designs rather than explicitly named copyrighted characters.
Maintain the original visual concept and humorous character interaction while improving:
anatomy
proportions
facial construction
hands
limbs
hair flow
wings
swimwear construction
accessories
lighting
skin rendering
water effects
environmental detail
wherever necessary for a more natural, balanced, and professionally illustrated result.
Allow small adjustments to posture, limb placement, hair, wings, clothing, and accessories where necessary to correct anatomy or strengthen visual balance, but do not fundamentally alter:
the original scene
left-to-right character arrangement
storytelling
camera placement
pose relationships
existing figure-size relationships
Do not introduce exaggerated perspective, dramatic wide-angle distortion, or major character repositioning simply to create additional depth.
Preserve the source image's moderate perspective and character-scale balance:
left reporter slightly closer → centre commander at the primary middle distance → right photographer modestly farther back
The differences in apparent scale should remain restrained and consistent with the reference.
Use smooth and sophisticated contemporary anime rendering with:
carefully controlled line weight
thin-to-medium tapered outlines
subtle painterly gradients
clean colour transitions
soft ambient occlusion
delicate reflected colour
finely layered highlights
softly dimensional form modelling
controlled environmental reflections
luminous warm skin tones
transparent water droplets
damp hair highlights
warm sunlight interacting with cool stream reflections
Avoid excessively flat cel shading.
Avoid heavy photorealism.
The characters should possess a gentle three-dimensional presence while remaining unmistakably anime in design.
A major visual priority should be the interaction between:
soft luminous skin + transparent water droplets + bright summer sunlight + damp hair + reflected blue-green stream light
I am still tremendously busy with my current main researcher job as I am in the middle of the research project under a strict supervision for the time being.
Also, the heatwave has come again, which is currently draining my energy and motivation for many thing on the top of it.
Therefore, I am playing with the AI again to make the synthetic art experiment.
As the Touhou Project popularity poll is going to be open from 21 to 28 August this year, I want to advertise for one of my favourite characters I will vote, Yuyuko Saigyouji together with my top favourite Myon-chan (Youmu Konpaku). I want to support both characters from Hakugyokurou to increase and sustain their popularity!

Yuyuko-sama — Posing for Modelling
Redraw this illustration as a polished early-to-mid-1990s Japanese fantasy RPG key illustration, reflecting the elegant visual language of Japanese fantasy strategy games, anime illustration books, and romantic shōjo-fantasy artwork from approximately 1991–1995.
Improve the line quality, anatomy, proportions, and shading while preserving the original composition.
Keep the original background, colour scheme, character pose, figure placement, and overall composition intact.
The finished artwork should feel like a refined Japanese fantasy game illustration or premium anime visual collection piece from the early-to-mid 1990s, with elegant linework, softly dimensional colouring, and a slightly romantic shōjo-fantasy atmosphere.
The facial rendering should lean slightly toward a graceful shōjo-fantasy sensibility.
Do not render the eyes in an excessively sharp, severe, or strongly shōnen-manga style.
Keep the eyes elegant, luminous, softly shaped, and emotionally readable.
Use delicate facial features, graceful eyelashes, softly layered irises, and controlled highlights without making the eyes oversized or excessively modern in appearance.
Her expression should appear graceful, serene, mysterious, and gently playful.
Use a landscape composition with a width-to-height aspect ratio of 1.414:1, matching the international A-series paper proportion and suitable for high-quality A3 or A4 printing.

Lately, I’ve been busy with my main job and have no air conditioning in my room, making it hard to focus on creative work due to my primary research duties. Today, I scanned a rough sketch and finished it using a mix of AI tools. I also made this as an example of creating free AI art with ChatGPT.
The prompt grew iteratively. Each unsuccessful generation revealed another ambiguity, so I kept adding more precise constraints until the result came close to the composition in my mind. In that sense, the final prompt is almost an archaeological record of my negotiations with the model.
The image is not only my idealised vision of Touhou Project, but also my own philosophical allegory. The three figures above represent hereditary, ritualised authority and the power of tradition. Sanae, as a modern progressive arriving from the twenty-first century, and Youmu, imagined as a solitary and disciplined swordswoman, confront them from below. Together, the two heroines represent different aspects of the player—essentially, different aspects of myself.
The input prompts are as follows:
This video presents our recent research on financial volatility forecasting, comparing classical econometric models, signal-processing techniques, and modern machine-learning approaches.
The study evaluates the forecasting performance, volatility prediction accuracy, computational efficiency, and interpretability of five different methods:
• GARCH
• SARIMA
• Matrix Pencil (MP)
• XGBoost
• Long Short-Term Memory (LSTM)
Using Bitcoin returns as a high-volatility financial asset, we investigate whether modern AI-based methods consistently outperform traditional forecasting techniques when accuracy, explainability, and computational cost are considered simultaneously.
Our results show that:
✓ SARIMA achieves the lowest return forecasting error.
✓ Matrix Pencil delivers comparable forecasting accuracy with extremely low computational cost.
✓ XGBoost provides a strong balance between accuracy and efficiency.
✓ LSTM exhibits relatively strong performance in tracking volatility patterns and market regime changes, despite higher forecasting errors and computational requirements.
✓ No single model dominates across all evaluation criteria.
The findings suggest that the Matrix Pencil method remains a competitive and highly interpretable alternative to black-box machine-learning models for financial forecasting applications.

I have asked ChatGPT to redraw my illustration of Cirno-chan and Myonchan (Youmu) shown below with the 90s Japanimation style.
I have tried to use PixAI, but it charges me money so that I have given up. The AI art, which we often see, actually costs money and requires some technique, which is kind of difficult, to generate what we want.
ChatGPT maybe useful for generating a synthetic image (hand drawing + AI redrawing), but it offers free image generation only times in total within a 24-hour period.
Hence, from my perspective, it is much easier for me to hand draw myself.
Merry Christmas everyone!

* AI hybrid experiment*
Asked ChatGPT to redraw some unfortunate illustration with critical mistakes.
A set of these illustrations is a redrawn version by ChatGPT, of the following works

Used in these short films:
My feedback on AI art (both pure and hybrid):
This is actually my first attempt at creating AI art. However, rather than instructing an AI tool to generate artwork via a command prompt—such as using Python in Stable Diffusion—I used an illustration I had already created and had the AI—ChatGPT, in this case—process it.
It is an interesting experiment to upload my already made images to an AI tool such as ChatGPT to redraw it. The AI corrects the crucial mistakes I have made while transforming to a popular art style. It can be useful for cases like
The drawback is losing my style of characteristics in these arts after the AI process. While observing various AI arts, the art style of these AI tools seems to be quite unified to the certain extend. AI is still generally limited to reproducing art styles that are well represented in its training data such as historically famous or currently popular arts. Because a unique art style of the user is usually undermined, it is not suitable for creating one piece of their impressive art.
Furthermore, only a very limited number of files are available process with these AI tools for a free option. It can be far less efficient to continue processing an image with AI in order to achieve the desired result than simply using traditional hand-drawing techniques.
In conclusion, AI art in any form has pros and cons. It depends on its application and the characteristics of the user's art skill. I may use the AI in some situation such as when I need a mass production of images. On the other hand, I am confident in my own drawing technique even though it might not perfectly match with what the popularity requires at the moment. Moreover, I am passionate to keep practising and improving my art technique. Hence, the AI process is useful as a supplement; not a substitution.
