Realistic Bedroom Selfie Portrait

Create an ultra-realistic vertical smartphone selfie portrait of a young woman in a cozy bedroom, photographed at close range with natural window light. The subject is {argument name="person" default="a young woman in her early 20s"} with {argument name="hair color" default="dark brown hair"} styled in a messy high bun with loose face-framing strands and flyaway hairs, thick natural eyebrows, brown eyes, long lashes, clear dewy skin with subtle pores and a few small blemishes, and soft neutral pink lips. She looks directly into the camera with a calm, slightly intimate expression while her right hand is raised over her mouth as if blowing a kiss; visible natural nails and a thin gold ring on the ring finger. She wears {argument name="top" default="a ribbed dark brown scoop-neck henley tank top with small buttons and scalloped trim"}. Compose the image as a tight head-and-shoulders portrait, face filling most of the frame, slightly tilted angle, cropped from upper chest to above the bun, with shallow depth of field. Background: softly blurred bedroom interior with warm beige walls, a bedside lamp glowing on the left, a small green plant, a framed wall print reading {argument name="wall print text" default="Good Things Take Time"}, a bed edge, and a white door with a dark handle on the right. Lighting should be soft and flattering, realistic skin texture, no heavy makeup, no airbrushed plastic look. Use natural colors, high detail, candid Pinterest-style realism, as if captured on a modern phone camera, vertical 9:16 aspect ratio.
