春日街头拼贴人像海报

Create a vertical youthful street-style collage portrait poster based on the uploaded portrait photo. Only use the uploaded portrait as the identity reference for the person's real facial features, face shape, hairstyle, hair color, and overall vibe. Do not copy the identity of the person in the reference image. All clothing, pose, scene, composition, and visual style should follow the reference collage image. The final image should be a vertical multi-photo collage poster. In the center, show the same real person in a full-body standing pose, wearing a light blue denim jacket, white inner top, loose light blue jeans, and white casual sneakers. The pose should feel relaxed and natural, with a bright, youthful, fresh, spring-like mood. The background should be an outdoor spring scene with blooming flower trees and a blue sky, with realistic natural sunlight and a real photography look. Add multiple white hand-drawn photo frames as collage elements: top left: a close-up of one eye / eye-area portrait; top right: a half-body shot making a peace sign; bottom left: a full-body sitting pose under the flowering trees; bottom right: a close-up portrait resting the face on one hand with a soft smile. All smaller photos must show the same person consistently, with matching identity and hairstyle. Use a dark street-graffiti style collage base, decorated with white sketch frames, pink and cyan neon outlines, hand-drawn hearts, stars, arrows, doodle lines, and playful graffiti accents. Replace the text with more suitable youthful spring-themed English graffiti words such as: "BLOOM SNAP", "SUNLIT YOUTH", "FLOWER MOOD", "FRESH DAY". The text should look like hand-drawn street graffiti integrated naturally into the poster, not formal typesetting. Overall style: realistic photography mixed with a youthful magazine-collage and street-graffiti poster aesthetic. Bright colors, natural sunlight, real skin texture, no plastic skin, no anime feel. High resolution, clean composition, rich layers, visually complete, suitable for a social media cover. No watermark, no platform logo, and do not include any "AI generated" text.
