Candid UGC smartphone dressing-room mirror selfie of a young woman, head turned in three-quarter profile with a playful slightly-open mouth, one hand raised holding a phone with an orange camera-module case and handwritten text on the back, the other arm lowered at her side. Exactly two arms and two hands, anatomically connected, clean natural fingers with neat nails gripping the phone, no extra limbs. Black square-neck sleeveless dress, colorful rhinestone gem stickers scattered across cheek, forehead, neck, collarbone, shoulder and arm in pink, orange, green, purple and silver stars and rounds, long dark hair half-up with loose face-framing strands, soft glossy makeup. Gray curtain backdrop, clothing rack with wooden hangers and garments at the right including a white textured dress and black top, dark leather sofa in the foreground, plastic cup with straw and a white drink at the lower left, paper tag hanging at the bottom center. Soft even indoor light, neutral cool tones, gentle shadow falloff, realistic phone-camera exposure. Vertical mirror-selfie framing from head to waist, subject centered, casual playful composition, slight grain, authentic idol practice-room selfie character.
