Ultra realistic cinematic full body portrait of a young man sitting in the ground

Create an ultra-realistic full-body men's fashion editorial photograph of a young male model sitting casually on the ground beside a modern raw-concrete wall. He has naturally messy, textured black hair and a relaxed, confident expression, looking directly at the camera. He is wearing an oversized burnt-orange and black plaid flannel shirt over a clean plain white crew-neck T-shirt, paired with loose-fit dark charcoal gray baggy jeans and clean white low-top sneakers. Add a subtle silver chain necklace, small earrings, and a black beaded bracelet. Pose: sitting in a relaxed crouched position with both knees bent and spread naturally, one elbow resting on the knee and one hand gently supporting the chin, while the other hand hangs naturally between the legs. Keep the posture effortless and stylish. Background: minimalist modern concrete architecture with large dark-framed glass windows, gray tiled pavement, subtle greenery in the distance. Soft natural daylight, muted neutral tones, cinematic shadows, shallow depth of field, realistic skin texture, detailed fabric, natural proportions, premium streetwear fashion photography, 85mm lens, f/2.0, soft bokeh, high dynamic range, editorial magazine quality, photorealistic, 4K, vertical composition, full body visible from head to shoes.
