PROMPT:
Create a mesmerizing image of an ancient, mysterious underwater ruin, submerged beneath the waves of a crystal-clear turquoise ocean, illuminated by shafts of sunlight that pierce through the water's surface, casting an ethereal glow on the scene. Incorporate an array of vibrant colors, with a focus on blues, greens, and yellows, to bring the forgotten metropolis to life. The architecture should be a mix of crumbling stone structures and overgrown with colorful seaweed and coral, teeming with exotic marine life, including schools of iridescent fish and majestic sea turtles gliding through the wreckage. Ensure the image appears photorealistic, with intricate textures and subtle water distortions, as if the viewer is exploring the site themselves.
