Realistic Portrait of a Young Woman in a Train Cabin

Based on <User Portrait>, a young adult woman inside a sunlit train cabin, calm direct gaze, natural realistic expression.

      "pose": "seated casually, leaning slightly back into a blue transit seat, shoulders relaxed, face centered toward the lens"

Wearing a dark high-neck knit top, a light cream jacket draped open around the shoulders, and a short black mini skirt with a clearly short hemline. Not a long skirt, not a midi skirt, not knee-length.

Very close low-angle seated portrait, camera placed close near lap height, 24mm wide-angle lens, tight vertical crop, face large in the upper center of the frame, foreground softly blurred, very little empty headroom.

Warm sunlight pouring from the right-side window, soft rim light on hair and cream jacket, bright window bloom, deep navy shadows on the knit top. Fujifilm Classic Negative inspired color grading, nostalgic Japanese train snapshot, analog film grain, soft halation, shallow depth of field, realistic skin texture.
