안개 낀 골목에서 차원을 지키는 스팀펑크 자동견

A steampunk automaton dog, brass gears whirring and clockwork heart ticking, guards a hidden portal in a fog-shrouded Victorian alleyway. Intricate pipework and glowing vacuum tubes adorn its metallic body. The scene is rendered with the detailed, atmospheric quality of dark fantasy concept art, infused with the gritty realism of steampunk aesthetics.
