Reverse punch

The prompt

Three-quarter view medium-wide shot of an elderly Okinawan karate master with a white goatee and a faded black belt on a stone terrace above the sea at dawn, high-contrast black-and-white film look, slow motion, locked camera. 0–2s: he settles into a front stance, left hand extended as a guide. 2–5s: his hips turn sharply forward as his rear right fist drives straight out, the left hand pulling back to his hip at the same moment. 5–8s: he holds the extended punch perfectly still, then exhales. Throughout: full body visible, waves breaking softly far below, wind moving his gi, fixed camera.
