Gigantic steampunk airship over floating islands and ruins

An enormous, steampunk-inspired airship, adorned with brass and intricate clockwork, navigates through a sky filled with floating islands and strange, bioluminescent creatures. Below, a vast, post-apocalyptic wasteland stretches to the horizon, dotted with the ruins of ancient cities. The style is a blend of retro-futuristic aesthetics and dark fantasy illustration, with a cinematic feel and a muted color palette.
