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

Create one independent high-end editorial poster for each uploaded photo. Do not combine multiple photos into a collage. Each photo must be processed and output as a separate poster. IMPORTANT: Remove the entire top-half original photograph section. The final poster must contain only the bottom-half hand-drawn paper illustration, expanded to fill the entire 3:4 canvas. The illustration must be based directly on the uploaded photograph and preserve the most recognizable visual elements, including the main subject, essential silhouette and proportions, key pose or gesture, important objects, and the core narrative relationship between people and objects. Highly simplify the image while keeping it immediately recognizable. Use delicate, slightly imperfect hand-drawn lines, a small number of bold acrylic-style flat color shapes, rough paper texture, visible handmade brush marks, slightly irregular organic edges, and subtle handmade imperfections. Keep the illustrated subject relatively small and centered, surrounded by a large amount of negative space. The entire background should resemble rough white paper, warm off-white paper, pale natural paper, or minimal editorial book-cover stock. Use only a few lines or small color shapes to suggest the surrounding environment. Extract the dominant colors directly from the original photograph and reduce them to no more than 4 main colors. Keep the palette restrained, sophisticated, and harmonious. Preserve subtle paper grain and handmade brush texture.A small amount of understated editorial typography may be added when appropriate, such as a short title, keyword, location, year, number, or short phrase. Do not force typography if it does not naturally fit. Visual direction: Quiet, poetic, refined, minimal, innocent, relaxed, artistic, thoughtful, highly recognizable, and premium. The concept should feel like: “A small subject surrounded by a large amount of empty space.” The final result should resemble a carefully designed independent art publication cover rather than a commercial advertisement. Do not include any photographic section, realistic photo, split-screen layout, collage, colored-pencil aesthetic, crayon texture, or bleeding watercolor. Final output: 100% hand-drawn paper illustration filling the entire 3:4 vertical poster.
