Fashion Portrait of East Asian Woman by Train Window AI Image Prompt

Create a photorealistic vertical fashion portrait of an adult East Asian woman, about {argument name="age" default="24"} years old, standing inside an older commuter train beside an open window on a bright sunny day. She is leaning forward with both hands resting on the metal window ledge, torso turned back over her shoulder to look directly at the camera with a soft, calm expression and slight smile. She has {argument name="hair color" default="long dark brown hair"}, loose and windblown across her face and down her back, natural makeup, clear skin, and delicate facial features. Outfit: a semi-sheer pale beige short-sleeve cropped top with side tie strings and fitted blue denim cuffed short shorts with visible back pockets and stitching. Composition is a three-quarter rear view from mid-thigh upward, centered slightly to the right, with the train window framing her upper body and a blue vinyl train seat partially visible at lower left. Background outside the window is overexposed and softly blurred, showing green trees and indistinct buildings. Use natural backlighting, warm sunlight, airy highlights, shallow depth of field, realistic skin texture, soft lens bloom, subtle film-like color grading, and high-detail editorial photography. Canvas: vertical 9:16 smartphone aspect ratio. Constraints: adult subject only, tasteful fashion photography, no nudity, no explicit pose, no text, no watermark, no extra people.
