Flash phone mirror selfie in upscale restroom AI Image Prompt

A candid smartphone mirror selfie in a moody upscale restroom with deep {argument name="wall color" default="crimson red"} textured walls and a large round mirror with a thin black frame dominating the composition. A {argument name="subject" default="young woman"} with long {argument name="hair color" default="dark brown"} wavy hair stands slightly off-center, leaning her torso forward and to the side in a relaxed confident pose, one hand holding the phone in front of her face and the other braced on a dark stone or marble countertop. She wears a fitted black off-shoulder long-sleeve top with a sweetheart neckline and high-waisted charcoal or black jeans, with a black shoulder bag tucked under one arm. The phone flash is extremely bright, fully obscuring the face and creating a sharp starburst plus 1 strong horizontal blue-white lens flare streak across the image, with subtle bloom and realistic smartphone exposure clipping. Behind her is a dark wooden paneled door centered in the reflection. The room includes 2 tall cylindrical wall sconces with warm glowing bulbs, one on each side near the mirror edges, 1 small gold-toned light switch plate on the left wall, 1 curved brushed-metal faucet visible at the bottom center, and 2 small candle holders or votive lights at the lower right edge. Style is authentic phone-camera photography, slightly grainy, warm low-light ambience, realistic reflections, minor sensor noise, natural shadows, intimate nightlife restroom aesthetic, vertical portrait framing.
