Steampunk Airship Soaring Above Sea of Clouds at Sunset

Cinematic realistic photography, a steampunk airship above a sea of clouds at dusk: The subject is a massive copper airship, with oval canvas gasbags pieced together in antique bronze and dark brown, featuring visible stitching and repair marks on the surface. The hull is made of riveted brass and dark wood, with a four-blade propeller spinning at the stern.
