Realistic Smiling Selfie Portrait

Create a realistic vertical smartphone portrait photo of an adult subject taking a close-up selfie from a slightly high angle, cropped from the upper arms to the top of the head. She has shoulder-length hair_color with soft layered waves, thin straight see-through bangs falling over her forehead, and glossy dark eyes looking directly into the camera. Her expression is warm and charming with a **gentle smile**, showing teeth slightly, with natural rosy makeup, soft blush, subtle eyeliner, and dewy skin. She wears a sleeveless ribbed knit halter-style top in top_color with tiny scattered black dot embellishments, plus exactly 2 visible necklaces: one short pearl necklace and one fine silver chain necklace with a small oval pendant. Her arms are folded casually near the bottom of the frame. The background is a plain rough gray concrete wall with small dark speckles and seams, giving an urban indoor studio feel. Use natural soft lighting, shallow depth of field, realistic skin texture, candid selfie composition, muted cool tones, high detail, no text, no watermark.
