PROMPT:
A fantastical, sprawling underwater metropolis, teeming with marine life, where iridescent fish swim alongside curious merfolk, exploring the vibrant markets and majestic architecture of the submerged city, as a brilliant, sunlit ocean surface gleams above, refracting light into dazzling shades of turquoise, emerald, and sapphire, with bursts of bright orange and yellow accents, while a colossal, gleaming aquamarine statue of a mythical sea creature towers in the background, surrounded by lush, undulating seaweed and coral formations.
