Photorealistic live-action music video footage. <Picture 1> is the artist: keep her exact face and hairstyle. Scene: a beach at blue hour, soft waves behind her. She wears a silver metallic halter mini dress. Action: she is walking away from the camera, seen from behind, face not visible. Camera: profile side view, smooth lateral tracking, 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.
