Spinning back kick

The prompt

Over-the-shoulder shot from behind a sparring partner holding a kick shield, an Iranian woman in a black taekwondo uniform and a sports hijab throws a single spinning back kick, in a dim training hall lit by a red exit sign and cool skylights, cinematic, slow motion. 0–2s: she faces the camera past the partner's shoulder in a fighting stance. 2–4s: she turns her back to him, eyes locking on the shield over her shoulder. 4–6s: her rear leg drives straight back like a piston, heel first, slamming the shield into the partner's chest and knocking him back a step, the camera jolting with him. 6–8s: she turns forward and lands in her stance, guard up. Throughout: her full body visible, the partner's shoulder and shield framing the left edge, dust drifting in the skylight beams.
