写实校园肖像，含身份参考

Use the uploaded portrait only as the identity reference. Accurately preserve the person's real face shape, facial features, skin tone, hairstyle, hair length, hair volume, and natural personal presence. Do not copy the original background, lighting, clothes, pose, or image quality from the uploaded portrait. Create a highly realistic candid campus photo, like a real handheld smartphone snapshot taken outdoors on a sunny school day. The person is standing on a quiet campus road under dense green trees, facing the camera with a soft natural smile. One hand is raised near the face making a casual peace sign gesture. The pose should feel relaxed, youthful, friendly, and spontaneous, not overly posed. The background should show a real campus environment: leafy trees, strong summer sunlight filtering through the branches, dappled shadows on the pavement, a simple school building in the distance, soft greenery, and a calm outdoor atmosphere. Use bright natural backlighting from above and behind the subject, with glowing sunlight around the hair edges, mild lens flare, slight overexposure in the highlights, and realistic shadow patches on the ground. Generate suitable casual campus-style clothing automatically based on the uploaded person's appearance. The outfit should feel natural, clean, youthful, and appropriate for the scene, with a relaxed school-day feeling. Do not add visible brand logos or readable text on the clothes. Camera style: handheld iPhone / mobile phone photography, vertical composition, medium close-up to half-body framing, slightly soft focus, natural motion blur, mild lens softness, realistic depth of field, imperfect but believable snapshot quality. The face should remain recognizable and natural, with real skin texture, no excessive beauty retouching, no plastic skin, no anime style. No watermark, no logo, no artificial text, no AI-generated label.
