AI synthetic Touhou fan-art: Yuyuko Saigyoji in Hakugyokurou - Tool: ChatGPT plus

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!

Elegant Pink-Haired Ghostly Noblewoman Illustration Prompt

Overall Art Direction

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.


Facial Design

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.


Canvas and Aspect Ratio

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.


Character

Elegant Pink-Haired Ghostly Noblewoman

An elegant ghostly noblewoman with short wavy pink hair and soft reddish-pink eyes, wearing a flowing light-blue-and-white traditional Japanese-style dress with dark blue trim and delicate floral motifs.

She wears a soft blue cap decorated with a white triangular spirit emblem.

Preserve her original pose and figure placement.

She should appear graceful, ethereal, refined, and aristocratic, with a mysterious yet gentle presence and a slightly playful smile.

Her overall presence should feel noble, beautiful, dreamlike, and quietly supernatural.


Supernatural Companions

Small Pale Ghostly Wisps

Several small pale ghostly wisps should surround the pink-haired ghostly noblewoman.

These ghostly wisps must remain light, soft, pale, semi-translucent, and spiritually atmospheric.

They should appear as simple floating supernatural wisps rather than fully formed creatures.

Do Not Add or Imply

  • human faces

  • eyes

  • mouths

  • noses

  • eyebrows

  • teeth

  • facial markings

  • expressive facial grooves

  • carved-looking features

  • heavily defined anatomy

  • monster-like details

  • mascot-like features

  • any recognisable human or animal face

Do Not Transform the Wisps Into

  • people

  • animals

  • mascots

  • monsters

  • skulls

  • humanoid ghosts

  • elaborate creature-like spirits

  • any supernatural beings with clearly readable faces

The wisps should remain soft, pale, floating spirit forms with clean silhouettes and a gentle supernatural presence.

Do not remove them or allow them to overwhelm the main figure.

They should support the atmosphere and character identity without distracting from the noblewoman herself.


Skin Tone, Texture & Luminous Warm Lighting

Skin Colour and Texture

Render the skin with a luminous warm ivory tone, soft peach undertones, and restrained natural pink blush.

Add subtle warm rosy colour to naturally flushed areas while keeping the overall complexion harmonious and refined.

Use smooth anime-style skin rendering with gentle translucent depth, creamy tonal modelling, subtle variations in skin colour, and soft warm gradients.

The skin should appear clean, luminous, softly radiant, and polished without becoming photorealistic.

Use restrained highlights to give the skin a delicate luminous quality while preserving the early-to-mid-1990s Japanese fantasy illustration aesthetic.

Avoid metallic, plastic, waxy, oily, or excessively reflective skin.


Warm Illumination

Use strong but elegant warm illumination consistent with the existing scene.

Create:

  • bright warm highlights

  • soft golden rim light around the hair and silhouette

  • warm reflected illumination

  • subtle amber bounce light

  • creamy illuminated areas

  • warm peach-coloured shadows

  • gentle tonal transitions between light and shadow

The brightest illuminated areas may become very luminous, but facial features, anatomy, linework, and colour information must remain clearly readable.

Use a pronounced but elegant contrast between luminous highlights and soft, warm shadows.


Reflected Colour and Dimensionality

Allow subtle pale rose, peach, amber, lavender, and blue-green reflected colours within shaded areas to create dimensionality, translucent depth, and atmospheric integration.

Use restrained soft bloom and gentle light diffusion around the strongest illuminated edges, particularly around the hair, silhouette, flowing sleeves, and selected bright contours.

The character should appear luminous against darker or cooler surrounding areas while remaining fully integrated with the original background.

The lighting should enhance the character without overwhelming the original scene.


Preserve the Original Environment

Preserve the original background, environment, character pose, figure placement, and overall composition.

Keep the lighting believable within the existing scene.

Do not introduce a new window, new architectural light source, photographic bokeh, shallow depth of field, or unrelated background lighting solely to create this lighting effect.

Instead, adapt the warm illumination, golden rim light, reflected colour, and highlight-to-shadow contrast to the light sources already present in the original illustration.

The final rendering should feel warm, luminous, dimensional, elegant, softly radiant, and highly polished, with the refined colour modelling of a premium early-to-mid-1990s Japanese fantasy RPG illustration.
