2x2 Sticker Grid with Hero Character

Generate a 9:16 vertical image according to the following instructions. This image must contain a clean 2x2 grid of FOUR separate sticker designs, each featuring the SAME hero character. The background MUST be pure white. **Hero Character Information:** * Hero Character Description: a chubby orange tabby cat with big green eyes and a purple collar (e.g., 'a chubby orange tabby cat with big green eyes and a purple collar') * If an image is provided: Preserve the hero character's identity, including fur pattern, eye color, collar/accessories, etc., from the provided image. * If no image is provided: Strictly follow the 'hero character description' and maintain consistency. **Sticker Phrases (Total 4):** * Sticker Phrase 1: Hello! * Sticker Phrase 2: Hungry * Sticker Phrase 3: Wow! * Sticker Phrase 4: Sleepy... * If phrases are not provided, invent short, funny meme-like phrases. Each sticker must contain exactly one short caption, ideally 1-4 words. **Style and Presentation:** * Style: Bold black line art, flat colors, minimal shading. * Genre: Clean cartoon sticker illustration (NOT 3D, NOT Pop Mart, NOT C4D). * Characteristics: Cute, expressive, slightly exaggerated. * Additional Decoration Elements: sparkles, sweat drops, question marks (e.g., 'sparkles, sweat drops, question marks, motion lines'). Leave blank if not needed. * Caption Text: Hand-lettered / marker style. * Each sticker must be a single 'die-cut' object: character + caption + decoration elements grouped together. * Add a clean sticker outline/cutline around each sticker, with a thin white border and a thin dark outer stroke. * Each sticker must have a subtle drop shadow (very light) on the white background, so it reads as a sticker placed on paper. **Poses and Reactions:** * Depict four clearly different poses and reactions. * Reactions must be communicated ONLY via facial expression, body language, additional decoration elements, and the phrase. * DO NOT use emotion labels such as 'confused', 'shocked', 'judgy', 'angry', 'sad', 'happy', etc. **Grid Layout:** * One image with a clean 2x2 grid: four stickers, evenly spaced, consistent scale. * Each sticker should be centered in its cell with generous padding for easy cropping. * DO NOT let stickers overlap, touch, or merge across cells. * No thick panel borders; grid separation should be clean whitespace spacing. **Background:** * Solid pure white across the entire canvas. * No gradients, textures, scenes, or colored blocks. **Text Rules:** * High contrast (usually black), readable, and correctly spelled. Do not use extra words beyond each sticker caption. **Negative Elements:** * No photorealism, no 3D/plastic toy render, no complex scenery, no extra characters (unless requested), no watermarks, no logos, no UI allowed.
