Create a vivid, high-detail digital painting of an underwater fantasy world. The scene is a deep blue ocean lit by soft bioluminescent glows and sunbeams from above. A lush coral reef blooms along the sides in pinks, purples, and blues. In the mid-water, several giant jellyfish with glowing pink-purple bells drift gracefully, their trailing tentacles glowing. A few sleek sharks glide near the center, while a friendly sea turtle rests on the sandy bottom. Small colorful fish dart around among the coral. A weathered wooden shipwreck lies on the left foreground. Bubbles rise, glowing orbs float, and the whole image has a magical, ethereal atmosphere with radiant blues and pinks, painterly texture, and cinematic lighting.
