Realistic Subway Candid Portrait

Inside a subway car, a {argument name="person" default="young woman"} is sitting on a seat near the door, looking down intently at her phone, not looking at the camera, with a natural and relaxed expression. She has exquisite features, delicate skin, and a clean, fresh temperament. Wearing {argument name="clothing" default="a simple white top, black skirt, and white sneakers"}, her long hair falls naturally. The subject is positioned at the right third of the frame, with a slightly blurred foreground obstruction on the left, resembling a candid snapshot perspective. The subway doors and handrails form vertical lines that guide the eye. The overall lighting is cool-toned subway light, soft overhead lighting, with natural shadows that are not overly strong. Shallow depth of field, the subject is clear, and the background is slightly blurred. The image has real camera grain and slight compositional imperfections, similar to street photography, not staged, high realism, and high detail.
