Prompt

A colossal ocean-going vessel designed as a complete floating metropolis, its immense ship hull supporting an entire vertical city of towers, bridges, residential blocks, elevated railways, observation decks, industrial machinery and layered streets. The underlying silhouette remains unmistakably that of an enormous ship, with a pointed bow cutting through the ocean and gigantic propulsion structures visible beneath the stern. Tiny conventional ships, tugboats and aircraft surround the vessel to establish its extraordinary scale, while countless windows and transportation routes illuminate the architecture. Wide three-quarter aerial composition emphasizing the complete silhouette of the machine and the city integrated into its structure, with the bow dominating the foreground and the urban superstructure rising toward the background. Highly stylized retro-futurist sci-fi illustration inspired by 1970s speculative-fiction paperback covers, saturated painted colors, exaggerated architectural forms, intricate hand-painted mechanical detail, dramatic cloud formations, graphic highlights and a dense sense of scale, richly illustrated rather than realistic.
