UPLOAD A REFERENCE IMAGE BEFORE GENERATING. MAIN PROMPT Using the uploaded photo as the primary reference, transform ONLY the main subject into a charming oversized-head hand-drawn cartoon caricature. The head must be dramatically exaggerated, approximately 45–60% of the character’s visual height, with a compact, much smaller body. Preserve the subject’s recognizable identity and defining characteristics while keeping the original photograph and environment fully recognizable. FORMAT LOCK Vertical 3:4. Preserve the original framing, camera angle, perspective, depth, subject placement, pose, orientation, and composition. Keep the photographic environment unchanged. STYLE TRANSFER Create a naïve children’s-book caricature with a deliberately huge, subject-specific head, enlarged forehead and cheeks, tiny simplified body, short limbs, small hands and feet, and a cute humorous proportion. Adapt the head shape, silhouette, hairstyle, hairline, facial hair, ears, beak, hat, helmet, or other defining features specifically to the original subject. Never use a generic circular head. DETAIL & COLOR Preserve facial structure, expression, skin tone, hairstyle, facial hair, clothing, accessories, patterns, logos, shoes, jewelry, and distinctive details. Use simple dot/oval eyes, tiny simplified nose, curved mouth, subtle cheeks when appropriate, soft natural colors, visible colored-pencil strokes, rough hatching, cross-hatching, uneven fills, overlapping strokes, imperfect edges, and subtle paper texture. COMPOSITION LOCK Transform ONLY the main subject. Keep the entire background photorealistic, including architecture, landscape, furniture, vehicles, scenery, lighting, depth, perspective, and atmosphere. Integrate the illustrated character naturally into the original scene with matching position, perspective, lighting direction, and subtle grounding shadows. STYLE Loose hand-drawn ink and colored-pencil caricature, charming, whimsical, naïve, expressive, handmade, slightly imperfect. Thin-to-medium organic black outlines, rough pencil texture, spontaneous sketch marks, simplified clothing, exaggerated oversized head, tiny body. The contrast between the realistic photograph and illustrated subject should be intentional and visually striking. NEGATIVE PROMPT Normal head proportions, small head, generic head shape, generic cartoon character, identical head shape across subjects, photorealistic subject, cartoonized background, fully illustrated scene, anime, vector art, 3D CGI, Pixar, Disney, glossy digital rendering, plastic texture, smooth gradients, polished graphics, altered identity, changed hairstyle, changed clothing, changed pose, distorted facial features, excessive facial detail, oversized body, realistic anatomy, unnecessary background changes. ASPECT RATIO: 3:4
