Streetwear trendy character poster from photo

Transform the uploaded person photo into a complete trendy character poster. The goal is not photorealistic reproduction, but extracting the person's recognizable traits and reconstructing them as a stylized character. Preserve the original person's hairstyle, face shape and vibe, expression, outfit colors, pose, shoes and key accessories so the source is recognizable, but the character must not look photorealistic. Character style requirements: exaggerated streetwear character, street-kid vibe, relaxed, confident, expressive, digital gouache poster style. Proportion requirements: head slightly larger but not chibi; neck slightly longer; torso smaller; body slim and elongated; limbs noticeably elongated; thin arms with clear elbow angles; slim wrists; slightly larger hands; long slender fingers with clear joints and posing; long slender legs with clear knee bends; slim ankles; shoes must be clearly oversized, with thick soles and a trendy toy-like feel. If the person is barefoot or wearing slippers/sandals, stylize and exaggerate the feet too, with correct toe count and a graphic, designed silhouette rather than a realistic foot. Body form requirements: proportions should not be close to real human proportions. Limbs should have a geometric, angular, long color-block feel. Elbows, knees, wrists and ankles need clear structure. Joints can be exaggerated but must remain believable. The pose should be relaxed and natural, such as crouching, half-squatting, sitting on the ground, throwing up a peace sign, spreading arms, or looking sideways at the camera. Avoid stiff standing poses. Hand requirements: hands are a key focus. Fingers should be slender, flexible, with clear joints. Gestures should feel natural, designed and street-style. Avoid extra or missing fingers, fused fingers, blurry hands or deformed hands. Facial features: features should be graphic, simplified and exaggerated. Avoid realistic skin texture, realistic eye highlights, or realistic portrait likeness. Use design-forward line work and bold color blocks for eyebrows, eyes, nose and mouth. Expression can be more exaggerated, confident and characterful than the source photo. Background: the background must match the character's stylization, not photorealistic. Rebuild mountains, water, tents, rocks, streets, rooms, furniture and objects from the original photo into graphic color blocks, thick brush strokes, collage fragments, graffiti lines, semi-transparent geometric shapes and abstract poster elements. The background can reference the original scene structure but must be flattened, simplified, symbolized and turned into poster art. Avoid a stylized character against a photorealistic background. Poster feel: the image should not be just a plain white background with a character. Add scene-appropriate graffiti text, handwritten marks, arrows, stickers, tape, rough brush strokes, abstract symbols and collage blocks. Use small accent words like FREE, VIBE, DAILY, CHILL, PLAY, SUMMER, WILD, GOOD VIBE, or short Chinese phrases. Text should not cover the face or hand gesture, should not become a formal title, and must not be garbled. Overall style: modern urban character poster, stylized streetwear character design, exaggerated proportions, long thin limbs, angular joints, oversized shoes, graphic facial features, expressive hands, long fingers, digital gouache painting, rough brush strokes, blocky color shapes, loose painterly edges, abstract poster background, collage elements, graffiti lines, handwritten notes, urban art zine style, fashion editorial poster, low saturation color palette, off-white background, strong poster composition. Final result: a premium streetwear character poster with clear joints, elongated limbs, detailed fingers, oversized shoes, relaxed pose and characterful expression. The background should also be unified into a thick-paint, collage, graffiti, graphic poster language. Negative prompt: no photorealistic person, no realistic portrait, no normal human proportions, no chibi roundness, no children's cartoon, no anime look, no 3D render, no plastic look, no realistic skin texture, no realistic eye highlights. Avoid short stubby limbs, normal shoe size, stiff standing pose, lack of joint structure, blurry joints, blurry fingers, extra fingers, missing fingers, fused fingers, deformed hands. Avoid photorealistic background, real photo background, a stylized character clashing with a photorealistic background, complex realistic landscapes, realistic photographic lighting, formal advertising headlines, garbled text, watermarks, logos.
