Generate your photo like this one. A young male standing confidently on a modern indoor staircase with glass railings. The setting is an architectural space with steel beams and large windows, creating a geometric background. He is wearing a light denim jacket over a striped shirt, coupled with black jeans and sneakers. A watch adorns his wrist and he holds a backpack casually in one hand. The image style is photorealistic with a soft focus, capturing vibrant light reflections and a slight lens flare effect.
