Prompt

A highly detailed illustration designed for jigsaw puzzle composition, featuring an ancient underwater library ruin hidden deep beneath the ocean in a mystical fantasy illustration style. Gigantic stone bookshelves tower through a vast submerged hall, their surfaces covered in vibrant coral reefs, glowing algae, sea moss, and drifting aquatic plants, while enormous whales slowly glide through the open library chambers, adding scale and wonder to the scene. Ancient books and scrolls float gently underwater between towering pillars and arched passageways, as glowing jellyfish drift through the space casting soft bioluminescent light. Schools of colorful tropical fish weave through broken arches and around cracked marble floors covered with sea plants and scattered ruins. Powerful rays of sunlight pierce through the deep ocean above, illuminating suspended particles and creating dramatic blue-green underwater lighting throughout the environment. The composition uses a wide-angle layered structure (foreground coral, books, and sea plants, midground pillars and marine life, background massive library halls and distant whales) to create strong depth and clear visual segmentation. Ultra-detailed underwater textures, cinematic fantasy atmosphere, rich aquatic color palette, atmospheric perspective, masterpiece composition, 8k resolution, perfect for a high-quality jigsaw puzzle.
