Granchio meccanico steampunk su rocce vulcaniche costiere

A highly creative, mind-blowing fantasy artwork of a steampunk mechanical crab forged from polished brass and rusted iron plates. The creature's heavily armoured shell is a complex mechanism of rotating clockwork gears, glowing copper pipes, and heavy rivets. White steam hisses out from its metallic joints as it sits proudly on a black volcanic coastal rock under a stormy sky. Brilliant ray tracing reflections on the metallic surfaces, sharp focus, epic sci-fi realism, Unreal Engine 5 render.
