Front punch

The prompt

Side-view medium-wide shot of a teenage Black girl karateka in a crisp white gi and brown belt in a sunlit wooden dojo, photoreal, locked camera at waist height. 0–2s: she stands in a long front stance, left fist guarding, right fist chambered at her hip. 2–4s: she steps forward, driving off her rear foot. 4–6s: her right fist shoots straight out once at solar-plexus height, twisting palm-down at full extension as her sleeve snaps. 6–8s: she pulls the fist back to her hip and holds the stance, exhaling. Throughout: full body visible head to toe, morning light through paper windows, polished floorboards, plain wall behind her, fixed camera.
