Steampunk Alien Airship Over Victorian London

An epic, high-contrast steampunk concept art featuring a colossal mechanical alien ship soaring through the misty skies above Victorian London near Big Ben. The alien vessel is engineered from polished brass, iron plates, and visible glowing copper clockwork gears. Thick clouds of white steam erupt from its blowhole, and golden searchlights shine from its metallic eyes onto the rain-slicked cobblestone streets below. Atmospheric fog, rich gritty metallic textures, sharp focus, masterpiece.
