Side punch

The prompt

Symmetrical front-facing wide shot of a middle-aged Korean taekwondo master in a black-trimmed white uniform, alone in an old wooden training hall at night, cinematic, slow push-in. 0–2s: he sinks into a deep horse stance, both fists chambered at his hips, eyes turning to his right. 2–4s: his right fist drives straight out to his right side at shoulder height, twisting palm-down, his sleeve snapping. 4–6s: it snaps back as his left fist punches straight out to the left side. 6–8s: both fists return to his hips and he holds perfectly still. Throughout: full body in frame, strong backlight through drifting haze, dust in the light beams, warm practical lamps, the camera creeping slowly closer.
