steampunk automaton 3d model

A broken-down non-humanoid steampunk automaton, now a motionless relic in a forgotten factory. The once-shiny brass and copper plating is now dull, heavily tarnished, and covered in green verdegris. The glass viewport on its boiler core is cracked and grimy. Its four powerful mechanical legs are frozen in place, with pistons rusted solid. The large cannon arm hangs limply. Exposed pipes are bent and leaking (stained with rust). The design incorporates dust, cobwebs, and signs of water damage. The pose should look defeated and inert, a ghost of its former power.
