霧に包まれたヴィクトリア朝ロンドン上空を飛ぶ巨大機械クジラ飛行船

An epic, high-contrast steampunk concept art featuring a colossal mechanical whale soaring through the misty skies above Victorian London near Big Ben. The whale 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.
