The Winter Walker Fashion Portrait

A photorealistic, full-body portrait of a handsome young man walking in front in a dynamic pose. He wears a black, high-puffer jacket with horizontal stitching, black tactical cargo pants, and pristine white high-top sneakers with white crew socks. He has short, dark curly hair and wears modern, black angular sunglasses. The setting is a clean, modern urban architectural space with a solid charcoal grey wall and a geometric light grey metal staircase in the background. The ground is a glossy, reflective black-and-grey polished stone, creating a sharp reflection of the subject. Use bright, hard daylighting to create a high-contrast, stylish look. High detail, 8K resolution, fashion photography, minimalist color palette (black, white, grey). Preserve the young man's features exactly as they are, without any alterations, ensuring 100% facial harmony and lighting. Then, edit the image using HDR with a glow effect.
