Hyperrealistic depiction of Underwater City, a city built beneath the ocean, with massive glass domes housing buildings and streets. Bioluminescent sea creatures swim outside the domes, casting a soft glow over the city. The streets are filled with people, some of whom have adapted to the underwater environment with gills or other modifications.Expansive fields of algae that emit a soft, greenish-blue glow, creating an eerie yet serene atmosphere. Tall towers made of crystalline structures that refract light into rainbow patterns throughout the city.Streets and walkways illuminated by embedded neon lights, guiding residents through the watery cityscape.Large, transparent fish tanks built into the walls and floors, filled with bioluminescent fish that light up the space.
