Photorealistic live-action music video footage. <Picture 1> is the artist: keep her exact face and hairstyle. Scene: a tiled underpass tunnel with a single flickering lamp. She wears a navy pinstripe vest and matching tailored shorts. Action: she is sitting on the floor, singing to the camera while stepping side to side with the rhythm. Camera: low angle, slow push-in, shallow depth of field. Do not generate: no outfit change, no text, no watermark, no extra limbs, no distorted hands, no duplicate person, no blurry face.
