Boxing Arena: Ring, Punching Bags, and Spectator Area

Render a Taiwanese boxing and martial arts gym occupying an old industrial floor. Show a full-size ring at one end with blue canvas, red and white ropes and corner pads, raised on a platform, lit by a cluster of industrial pendants directly above so the canvas is the brightest surface in the room. Along one side, hang a row of heavy bags from an exposed steel ceiling frame at even spacing, with speed bags on a separate wall rack. Lay puzzle mats in dark grey across a matted training area with a taped circle. Keep the building fabric raw: exposed concrete columns, brick walls with peeling paint, exposed ductwork and conduit painted black. Add a wall of hooks with gloves and wraps, a chalk-scrawled whiteboard of the day's rounds, a wall clock with a round timer, and a bench for spectators along one wall. Include fighters training and a coach holding pads. Show dramatic pooled lighting with dark surroundings. Photorealistic, gritty, sweaty and energetic, eye-level view toward the ring.
