A dark fantasy book cover design inspired by the mysterious dangers of the ocean depths, ancient maritime legends, and cursed treasures. The composition features an antique, rusted silver compass containing a swirling neon ultramarine vortex, set against the decayed wooden texture of a sunken galleon. A metallic skull relief adds an ominous atmosphere, while blurred bubbles, glowing plankton, and underwater light rays create a convincing sense of depth and immersion. Platinum typography completes the composition, contrasting with the dark, mysterious underwater setting. Created as a personal concept project using Adobe Photoshop.
