Potret Candid Ponsel di Kereta

Vertical close-up portrait of [a young Japanese woman with long straight black hair and wispy bangs] seated on a train, viewed from slightly above and very close in an intimate candid smartphone photography style. She is wearing [a beige oversized knit cardigan with long ribbed sleeves over a white collared shirt and dark plaid school-style ribbon tie]. She holds [a silver smartphone] in her left hand near the foreground, while her right hand is pulled inside the sweater sleeve, gently covering her mouth in a shy, playful gesture. Her expression is [softly smiling with warm eye contact, slightly bashful and mischievous]. Setting & Composition: Cropped tightly around her face in the upper center-right, upper torso, hands, and the phone in the left foreground. Seated beside a train window with subtle motion blur outside indicating travel, a purple seat visible at the left edge, a metal window frame on the right, and a small black leather bag partially visible at the lower left. Lighting & Style: Natural daytime window light, shallow depth of field, soft shadows, realistic skin texture, and natural color grading. Ultra-realistic modern candid aesthetic. No extra people, text, heavy makeup, or studio lighting.
