Ultra-Realistic Candid Street-Style Photo of Young Man in Grocery Market

Create an ultra-realistic candid street-style photograph of a young man in his early 20s as a reference image walking through a modern upscale grocery market. He is photographed from behind and slightly from the side as he looks over his shoulder toward the left. He has short, naturally messy dark brown hair and a slim athletic build. He is wearing an oversized dark navy Acne Studios hoodie with large white text on the back reading "Acne Studios Stockholm 1996", a matching dark navy baseball cap, and a black backpack worn over both shoulders. The hoodie has a relaxed oversized fit with natural fabric folds. The setting is a large premium supermarket with fresh produce displays, flowers, shoppers, escalators and industrial ceiling details. Warm indoor lighting mixed with natural ambient light. Candid photography, realistic skin and hair texture, natural body proportions, subtle motion, authentic smartphone camera quality, shallow depth of field, realistic background detail, understated luxury streetwear aesthetic, no artificial or CGI appearance. Vertical composition, 4:5 aspect ratio.
