Authentic Smartphone Selfie Portrait

A photorealistic close-up smartphone selfie of a {argument name="subject" default="young Japanese woman"} in a {argument name="setting" default="cozy bedroom"}, captured naturally with a front-facing phone camera. She has dark brown-black hair tied into a slightly messy low bun, soft wispy straight bangs, warm brown eyes, naturally fair skin, subtle rosy cheeks, minimal makeup, glossy pink lips, and a tiny beauty mark on her cheek. She rests one hand gently against her cheek while making a soft playful pout and looking directly into the camera. She wears an {argument name="clothing" default="oversized textured white sweatshirt"} with partially visible dark navy lettering. The background is a simple lived-in bedroom with warm off-white walls, a white curtain on the left, a small green houseplant, and a light wooden slatted closet/room divider behind her. Natural indoor daylight, slightly uneven smartphone exposure, subtle phone-camera grain, realistic skin pores and fine hair strands, mild lens softness, natural shadows, no studio lighting, authentic unedited mobile-photo appearance, casual candid composition, close framing, realistic proportions, high detail, vertical 3:4 aspect ratio.
