日本の若者の車窓ポートレートコラージュ

Use the uploaded portrait only for the person's facial identity, hairstyle, hairline, skin tone, and natural proportions. Create a realistic three-panel vertical photo collage inside the back seat of a car, soft sunlight streaming through the window, green trees and street outside with gentle motion blur. The person wears a clean school-uniform-inspired outfit, sitting near the car window, hair softly blown by wind, warm backlight glowing through the hair. Three natural expressions: looking at camera, looking sideways out the window, looking down with a slight smile. Soft dreamy Japanese youth-photo atmosphere, real smartphone photography, natural skin texture, gentle lens flare, shallow depth of field, 3:4 vertical composition, no watermark. Negative Prompt: anime, cartoon, plastic skin, over-smoothed face, fake doll look, exaggerated eyes, changed identity, copied face from reference image, harsh makeup, distorted hands, bad anatomy, low resolution, watermark, logo, text, overexposed face, unnatural lighting, AI artifacts.
