There is a very large underwater scene with a river and many corals

Imagine an underwater metropolis nestled within a vast coral reef, where skyscrapers made of translucent materials rise from the ocean floor. The city is illuminated by bioluminescent plants and jellyfish that float gracefully through the streets. Rays of sunlight penetrate the water’s surface, creating a mesmerizing dance of light and shadow. The overall mood is peaceful and otherworldly, with marine life seamlessly integrated into the city's design.
