Profile / Avatar - Candid Train Portrait

Create a vertical photorealistic close-up portrait of a young woman sitting on a train seat, viewed from slightly above and very close, as if photographed candidly with a smartphone. The subject is {argument name="character description" default="a young Japanese woman with long straight black hair and wispy bangs"}, wearing {argument name="outfit" default="a beige oversized knit cardigan with long ribbed sleeves over a white collared shirt and dark plaid school-style ribbon tie"}. She is seated beside a train window with blurred motion outside, suggesting the train is moving; include a purple train seat at the left edge, a metal window frame on the right, and a small black leather bag partially visible near the lower left. She holds {argument name="phone" default="a silver smartphone"} in her left hand close to the camera, while her right hand is pulled into the sweater sleeve and gently covers her mouth in a shy playful gesture. Her expression is {argument name="expression" default="softly smiling with warm eye contact, slightly bashful and mischievous"}. Use natural daylight from the window, realistic skin texture, detailed eyes, soft shadows, shallow depth of field, and subtle motion blur in the background. Composition should crop tightly around her face, upper torso, hands, and phone, with her face in the upper center-right and the phone in the left foreground. Style: ultra-realistic modern Japanese train candid portrait, high detail, natural color grading, intimate everyday atmosphere. Avoid text, logos, extra people, exaggerated anime features, heavy makeup, or studio lighting.
