Photorealistic live-action music video footage. <Picture 1> is the artist: keep her exact face and hairstyle. Scene: a dance practice room with a full-height mirror wall, pale wood floor, ballet barre, soft overhead fluorescent light. Her reflection is visible in the mirror behind her. She wears a black cropped tank top and loose grey sweatpants. Action: she is dancing hip-hop street choreography, bouncing on the beat with heavy grooves, body rolls, chest pops and sharp arm swings, low center of gravity, lips closed and still. Camera: eye level, smooth lateral tracking, shallow depth of field. Do not generate: no outfit change, no text, no watermark, no extra limbs, no distorted hands, no blurry face, no singing, no lip movement, no talking.
