PROMPT:
A mystical underwater metropolis inhabited by humanoid sea creatures, surrounded by luminous oceanic flora, vibrant coral reefs, and schools of iridescent fish, set against a radiant turquoise background, with majestic crystal palace structures, adorned with glittering gemstones, and majestic seaweed draped archways, lit by an otherworldly glow emanating from luminescent orbs, amidst a kaleidoscope of colors, excluding pink, with meticulously detailed textures, and an air of whimsical fantasy, as if plucked straight from the pages of a fantastical comic book.
