Bioluminescent underwater city 🐠🌊 An underwater city within a coral reef, with luminous fish and a whale shark, in a hyperrealistic digital painting style.

A fantastical underwater city built within a colossal, bioluminescent coral reef. Schools of luminous fish swim through archways carved from giant shells. A majestic whale shark glides past, its skin adorned with intricate, glowing patterns. The art style is a hyperrealistic digital painting with a focus on vibrant, saturated colors and a sense of awe-inspiring scale.
