Use the uploaded portrait only as the identity and hairstyle reference. Accurately preserve the person’s real facial identity, face shape, facial features, skin tone, hairstyle outline, hair volume, and natural real-life appearance. Do not copy the original photo’s background, lighting, clothing, pose, or image quality. Do not turn the person into an anime character, doll, idol illustration, or plastic-looking AI face. Create a highly realistic 9:16 vertical Y2K streetwear collage poster of the same person. The overall visual style should reference a neon graffiti magazine sticker-board layout: multiple cutout portraits of the same person arranged dynamically on one vertical poster, with thick white sticker outlines, subtle pink neon rim glow, layered photo frames, graffiti tags, doodles, spray-paint textures, black grunge background, electric pink and cyan accents, and a high-energy urban fashion poster feeling. The poster should include several different shots of the same person in one composition: one central full-body standing pose, one half-body playful pose, one seated or crouching pose, one close-up portrait, and one cropped detail frame showing one eye or facial detail. Each pose should have a different angle, expression, and framing, but all must clearly look like the same real person from the uploaded portrait. Generate suitable clothing automatically based on the uploaded person’s real appearance and style. The outfit should feel like stylish Y2K streetwear, possibly including denim, layered casual fashion, boots or sneakers, accessories, soft street-style details, and a coordinated youthful look. Do not lock the clothing to the reference image exactly. Choose clothes that fit the person naturally and look believable. Avoid overly revealing clothing. Use realistic photography texture: natural skin pores, real skin texture, soft uneven skin tone, natural lips, realistic hair strands, believable fabric wrinkles, correct body proportions, detailed denim or streetwear fabric, realistic hands, and real camera lighting. The person should feel like a real photographed person placed into a designed collage poster, not a 3D render or anime illustration. Lighting should be cinematic but believable, with soft neon pink and cyan reflections, subtle rim light around the cutout edges, realistic shadows, and clean separation from the dark graffiti background. Keep the composition polished, high-end, energetic, and social-media ready. Do not include any watermark, brand logo, AI-generated text, random Chinese characters, fake signatures, QR codes, platform labels, or unreadable typography. Any graffiti should be abstract decorative marks only, not readable text. The final image must be vertical 9:16.
