写实地铁素描肖像

A photorealistic first-person perspective inside a modern South Korean subway car. The scene features stainless steel poles, red and gray seats, overhead signage, and a detailed subway route map above the doors. In the foreground, a hand holds a spiral sketchbook and pencil. The sketchbook shows a highly detailed black-and-white portrait of a young man wearing a purple hoodie with graphic flame print. Across the subway, the same real person sits on a seat, matching the sketch exactly, wearing a purple graphic print hoodie and jeans, looking down at his phone. Cinematic lighting, sharp focus, depth of field, ultra-realistic textures, 4K detail.
