{ "prompt": "Use the uploaded image strictly as the identity and pose reference. Preserve the same person, facial structure, hairstyle, age, gender, body proportions, and overall likeness without adding or removing any person. Do not alter identity. Transform the subject into a hand-drawn storybook-style illustration created with colored pencils and soft watercolor washes.\n\nIllustration Style:\nHand-drawn colored pencil illustration with clean, confident line art and slightly rough, organic pencil outlines. Pencil strokes should be clearly visible and layered, giving a natural hand-drawn feel. Combine this with gentle watercolor wash textures that softly blend colors without overpowering the pencil lines.\n\nColor & Texture:\nUse bright pastel colors with lighter, cheerful, and vivid tones while keeping natural saturation. Colors should feel soft and cozy, never harsh or neon. Apply flat yet detailed coloring with subtle watercolor gradients. Minimal shadows, soft highlights only, no dramatic lighting. No realism, no photo texture, no hyper-detail.\n\nFacial Features & Expression:\nSimplified, cute facial features in a semi-cartoon realistic proportion. Dot-style eyes, small gentle smiles, soft rounded face shapes. Expressions should feel warm, friendly, innocent, and approachable. Keep facial details minimal but expressive.\n\nMood & Atmosphere:\nWarm, cozy, and cheerful atmosphere with a wholesome children’s book illustration feel. Friendly and comforting tone, suitable for a storybook or picture book. The overall mood should feel calm, joyful, and inviting.\n\nRendering Rules:\nHigh clarity illustration, clean edges, no blur. No photographic realism, no cinematic lighting, no 3D render, no digital painting look. Avoid heavy shading, deep shadows, glossy skin, or realistic textures.\n\nBackground:\nSimple, soft, illustrated background that complements the subject without distraction. Use pastel colors, gentle shapes, and minimal detail to maintain a storybook aesthetic.\n\nFinal Output:\nA cozy, cheerful, hand-illustrated children’s book style artwork with colored pencil linework and soft watercolor textures, maintaining exact identity from the uploaded image while transforming it into a warm, friendly, semi-cartoon illustration.", "negative_prompt": "photorealism, hyper-realistic, realistic skin texture, photo texture, cinematic lighting, dramatic shadows, dark tones, neon colors, glossy skin, 3D render, oil painting, digital painting, anime style, manga style, vector art, pixel art, blur, noise, grain, extra people, face change, identity change, exaggerated realism", "quality": "high", "clarity": "very high", "style_strength": "strong illustration style", "reference_usage": "face and identity preservation required" }
