Make “Split Poster Picture Book Portrait with Memphis Pattern” yours

Design as a split top-and-bottom layout, 3:4 vertical composition. The top half shows the subject from the user's uploaded original photo, focusing on extracting people, cats, dogs or other animals as the main subject, preserving as much as possible the subject's real facial features, hair/fur characteristics, body proportions, clothing or coat color, pose and overall expression; architecture and environment are de-emphasized to highlight the subject. The bottom half translates the same subject into a minimalist Japanese graphic poster style: a pure white background with fine silkscreen grain, tiny particle texture and halftone screen texture, giving an overall subtle hand-printed feel; the style references the picture-book quality of "a children's picture book by Atman," incorporating doodle-style hand drawing, dopamine color palette, print patterns, polka dots, a master's sketchbook feel, abstract deformation, and Memphis-style vector illustration. The subject is no longer fixed as a little lamb, but transformed according to the subject in the top half: if the top half is a person, turn that person into an abstractly deformed, cute, patternized human figure; if it is a pet, turn that pet into repeating pet patterns, print elements, and abstractly deformed pet silhouettes. The image uses asymmetrical graphic forms plus random combinations of dots, lines and planes, deliberately distorted and deformed to create strong visual impact; add repeating shapes, polka dots, motifs and print elements related to the subject, so the bottom half has both children's-book playfulness and Memphis visual tension. The overall feel is childlike, free, strongly graphic and visually striking, while keeping the white background, Japanese flat graphics, hand-drawn doodles and a highly recognizable subject. Do not generate any text, titles, logos, or watermarks.
