Sunlit Train Window Fashion Portrait

Photorealistic vertical fashion portrait of an adult East Asian woman, about [24] years old, standing inside an older commuter train beside an open window on a bright sunny day. She leans forward with both hands resting on the metal window ledge, her torso turned back over her shoulder to look directly into the camera with a calm expression and a gentle smile. She has [long dark brown hair] that is loose and windblown across her face and back, natural makeup, clear skin, and delicate facial features. Outfit: a semi-sheer pale beige short-sleeve cropped top with side tie strings, paired with fitted blue denim cuffed shorts showing back pockets and stitching. Composition: three-quarter rear view from mid-thigh upward, centered slightly to the right, framed naturally by the train window with a blue vinyl train seat partially visible at lower left. Background: overexposed, softly blurred scenery outside showing green trees and distant buildings. Lighting and style: natural backlighting, warm sunlight, airy highlights, shallow depth of field, realistic skin texture, subtle lens bloom, muted film-like color grading, high-end editorial lifestyle photography. Vertical 9:16 aspect ratio. Constraints: adult subject only, tasteful fashion aesthetic, no nudity, no text, no watermarks, no extra people.
