Generate an image of a massive, ancient underwater city, hidden beneath the waves for centuries. The city should be filled with intricate stone carvings, glowing bioluminescent plants, and schools of rainbow-colored fish darting through the streets. In the center of the city, a colossal statue of a mermaid queen should rise from the seafloor, her eyes glowing with an otherworldly energy. The image should be rendered in exquisite detail, with realistic lighting, shading, and textures that transport the viewer to an underwater world of wonder and discovery.
