masterpiece, best quality, high quality, ultra-detailed, 8K Ultra HD, dynamic waist-up portrait of a young man walking through a modern train station, warm brown skin, sharp jawline, full lips, dark amber eyes and a focused expression. Short curly black hair catches the cool overhead light. He wears a lightweight black ripstop windbreaker over a pale blue button-up shirt, relaxed pleated wool trousers and sleek leather loafers. A compact crossbody bag rests diagonally across his torso, while a silver watch and simple ring add subtle polish. Glass architecture, steel beams, commuters and cool evening light create a refined urban atmosphere.
