floating steampunk prison platform 3d model

Floating steampunk prison platform, large weathered wooden deck supported by rusted iron scaffolding, riveted steel beams and tar-stained rope rigging, suspended in warm sunset haze. Big square open cube cages dangle from the underside on heavy chains and pulleys, each cage entirely hollow, four wrought-iron lattice walls framing an empty box, nothing inside. Chunky industrial silhouette, plank decking, riveted plating, weathered timber, oxidized copper trim. Cranes, ladders, smokestacks and brass valves clutter the upper deck. Hazy golden hour light, soft volumetric mist, drifting smoke, distant skyline of similar floating rigs, painterly concept art style.
