Retrato de cuaderno de bocetos en el metro, estilo cinematográfico

Cinematic, hyperrealistic scene inside a modern subway train. A young man with styled brown hair, light stubble, and glasses sits on a blue seat, wearing a purple hoodie over a white t-shirt and light gray pants. He is slightly hunched forward, focused on his smartphone in both hands. Natural daylight streams through the train windows, creating soft highlights and realistic shadows. In the foreground, a hand holds a spiral sketchbook toward the camera. The sketchbook contains a highly detailed graphite pencil drawing of the same man in the exact pose, with selective purple coloring on the hoodie matching reality. The drawing is sharp, artistic, with fine shading, cross-hatching, and realistic proportions. Depth of field effect: foreground sketchbook in sharp focus, background subject slightly softer but still clear. Interior train details visible, including seats, poles, and a few blurred passengers. Clean composition, cinematic framing, 35mm lens, shallow depth of field, ultra-detailed textures, photorealism, 4K quality.
