A cinematic, surreal audiobook cover art capturing the vast, tempestuous Atlantic Ocean at dusk. In the center, the silhouette of a 15th-century wooden caravel ship is captured from a low angle, dwarfed by towering, dark, rolling waves under a dramatic, moody sky filled with swirling storm clouds and a single, piercing beam of moonlight. Deep navy blues, charcoal grays, and accents of burnt orange and gold on the horizon. The composition is highly detailed, emphasizing the texture of weathered wood and the foam of the sea. Ethereal, mysterious atmosphere, oil painting style with a modern, high-contrast digital polish, dramatic lighting, no text, no letters, no words, square format.
