Natural Indoor Selfie Portrait

Create an ultra-realistic vertical smartphone selfie portrait of a young East Asian woman with {argument name="hair color" default="straight black hair"} tied back in a low ponytail, with thin wispy bangs falling over her forehead and a few loose strands framing her face. She has large glossy dark brown eyes, soft natural eyebrows, smooth fair skin, rosy cheeks, subtle pink lips, and a gentle closed-mouth smile while looking directly into the camera. She is wearing a loose {argument name="sweatshirt color" default="light heather gray"} crewneck sweatshirt with ribbed collar and soft fabric texture. Frame her from upper chest to top of head in a close selfie composition, slightly angled from above, with her face centered slightly to the right and her shoulder filling the lower foreground. Use soft natural indoor daylight, realistic skin texture, shallow depth of field, and a clean beige wall background with a faint corner line and a small glimpse of neutral fabric furniture at the lower left. The mood should be calm, cute, casual, and candid, like an unedited phone camera photo. Vertical 9:16 aspect ratio, high detail, photorealistic, no text, no accessories, no watermark.
