ChatGPT用プロンプトサンプル

prompt
Please generate a sticker sheet containing exactly 8 separate LINE sticker images arranged in a clean grid layout, based on the provided reference character design.

## CHARACTER DESIGN

- Use the exact same character design from the provided reference image.
- Character: A friendly white-and-green kawaii robot with green headphones and a small green sprout on top of its head.
- Preserve the same face, body proportions, white-and-green color scheme, headphones, sprout, and overall character identity across ALL 8 stickers.
- Do not redesign or significantly alter the character.
- Each sticker should feature a clearly different pose and facial expression while maintaining perfect character consistency.
- Use rounded, adorable chibi proportions.

## ART STYLE

- Soft watercolor-style kawaii illustration.
- Warm, gentle, hand-painted watercolor texture.
- Cute Japanese stationery and LINE sticker aesthetic.
- Soft pastel colors with subtle watercolor variation and shading.
- Slightly textured watercolor fills.
- Clean but gently hand-drawn outlines rather than rigid digital vector lines.
- Bright, cheerful and highly expressive.
- Add small decorative elements where appropriate, such as:
sparkles, stars, hearts, motion marks, sweat drops, moon, sleep symbols, and excitement marks.
- Decorative elements should complement each emotion without making the composition too busy.

## COLORED SPEECH BUBBLES — IMPORTANT

Every sticker must contain ONE colorful speech bubble.

- Use large, cute, rounded, playful speech bubbles.
- Each speech bubble should have a bright watercolor-style colored fill.
- Use different cheerful colors across the sticker set, such as:
green, pink, orange, blue, red, purple, turquoise, and other harmonious pastel-bright colors.
- Speech bubbles may have slightly different organic shapes to match each emotion.
- Keep the shapes rounded, soft, friendly and kawaii.
- Avoid plain rectangular text boxes.
- Avoid rigid or corporate-looking speech bubbles.
- The speech bubble should feel like an illustrated part of the sticker.

## TEXT DESIGN — VERY IMPORTANT

Place the specified Japanese phrase inside each colored speech bubble.

The lettering must be:

- WHITE lettering inside the colored speech bubble.
- Large, bold and highly legible.
- Cute, playful, professionally designed Japanese display lettering.
- Rounded and hand-drawn in appearance.
- The lettering should look intentionally designed rather than like ordinary typed text.
- Slight variations in letter size, angle and baseline are encouraged to create an expressive hand-lettered appearance.
- Use thick, substantial letterforms suitable for small LINE stickers.
- Maintain strong contrast between the WHITE lettering and the colored speech bubble.
- Do NOT use black text.
- Do NOT use thin typography.
- Do NOT use plain system fonts.
- Do NOT use serif fonts.
- Do NOT place the text outside the speech bubble.
- Spell every Japanese phrase exactly as specified.
- Do not add translations or additional words.

The overall effect should resemble cute Japanese hand-lettered sticker typography:
bold, rounded, expressive, playful, and highly readable.

## WHITE STICKER BORDER — CRUCIAL

Every complete sticker must have a thick, clean WHITE outer sticker border.

The white border must surround the ENTIRE sticker composition, including:

- character
- speech bubble
- text area
- hearts
- stars
- sparkles
- motion marks
- accessories
- decorative elements

The character and speech bubble should visually form ONE complete sticker unit.

Each complete sticker must remain completely separated from every other sticker.

## GRID LAYOUT

Create EXACTLY 8 stickers.

Arrange them using:

- 2 to 3 columns
- 2 to 4 rows

Recommended layout:

Row 1: 3 stickers
Row 2: 3 stickers
Row 3: 2 stickers

A 3 + 3 + 2 arrangement is preferred.

Perfect vertical column alignment is NOT required.

Prioritize generous separation and balanced composition over rigid alignment.

## SPACING — EXTREMELY IMPORTANT

Every sticker must be completely isolated from neighboring stickers.

Leave clear, continuous transparent space:

- between every column

No part of one sticker may touch another sticker.

This includes:

- white borders
- speech bubbles
- text
- characters
- stars
- hearts
- sparkles
- motion marks
- shadows
- decorative effects

Leave AT LEAST 10 pixels of fully transparent padding on the TOP, BOTTOM, LEFT and RIGHT sides of EACH complete sticker unit.

The 10-pixel transparent padding must exist OUTSIDE the white sticker border.

There must also be sufficient transparent separation between rows so that each sticker can be automatically detected and cropped as an independent object.

Do not allow decorative elements or white outlines to create bridges between neighboring stickers.

## BACKGROUND

- Transparent PNG background.
- True alpha transparency.
- No white background.
- No colored background.
- No scenery.
- No background pattern.
- No checkerboard pattern rendered into the image.
- The space surrounding and separating all stickers must remain fully transparent.
