Photo × Modernist Poster Diptych

Create a complete vertical illustration in a top-and-bottom diptych style: split the portrait canvas into two regions of equal height, with a distilled rendering of the original subject in the top half and a Modernist Poster reinterpretation in the bottom half. Keep the overall composition simple and clear, with the feel of a modern graphic poster. Top half: Use the uploaded image as the only reference for the subject. Automatically identify and extract the person, cat, dog or other common pet, and focus on preserving the subject's identity; do not make buildings or complex surroundings the main content. Preserve as much as possible of the person's face shape, facial features, hairstyle, clothing, apparent age, bearing and accessories, or the pet's breed, coat color, markings, facial features and build. Simplify the background; keep the subject clear and whole, with a stable visual center. Bottom half: Turn the same subject into a complete illustration in the visual language of the "Modernist Poster". Core style traits: accurately extract the most characteristic line, color, composition and material language of this style, keep it consistent, and do not mix it with other styles. Overall principles: use clear geometric structure, flat blocks of color and an orderly composition, with controlled hierarchy and negative space. Compose around a single clear subject or one clear scene with a stable visual center; keep the subject whole and uncropped, and simplify the background moderately while leaving room to breathe; line, color blocks, light and shadow, materials and paper texture must all serve the same style, with no unrelated styles mixed in. The bottom half should show the simplified forms, clear visual center, strong flatness, structural composition and a limited, unified color order common in Modernist poster language, so that the subject is reorganized within a Modernist design system. The image should feel natural and handmade, with recognizable style traits; avoid the over-smooth finish, meaningless piles of detail and random decoration common in AI images. Overall requirements: The subjects in the top and bottom halves stay clearly consistent; the bottom half is a Modernist-poster reconstruction of the subject in the top half. Unless the subject explicitly calls for it, do not generate text, logos, watermarks, borders or UI, and do not make a multi-image collage.
