Windmill Engine: Robotic Concept Art Inside Sails

Hyper-detailed concept art of a humanoid robot inside a windmill. Inside the aged timber windmill, massive wooden gears, brass pipes, and suspended belts drive the sails. A sleek humanoid robot with polished chrome plating and matte carbon-fiber panels stands at the center, its blue eyes glowing. It touches a brass control lever while a wooden cogwheel turns nearby. Sunlight pours through slatted windows, casting long shadows and dust motes across a stone floor. The scene blends steampunk and cyberpunk aesthetics, with riveted metal, weathered wood, and oil-slick textures. Outside, the open doorway reveals wind-swept fields and towering blade silhouettes. Cinematic lighting, dramatic perspective from a slightly low angle, and rich micro-detail to support a concept art mood.
