PROMPT:
A dynamic comic book-style artwork depicting a fantastical underwater metropolis, teeming with peculiar sea creatures and eccentric architectural marvels, set against a radiant turquoise background that gradates to a soft golden hue towards the top, illuminated by a mesmerizing spiral-shaped luminescent portal radiating vibrant shades of electric blue, emerald green, and sunshine yellow, with an ancient, gnarled tree emerging from the depths, its twisted roots morphing into majestic stone pillars supporting a grand, intricately carved domed palace at the heart of the metropolis, surrounded by bustling sea creatures, including a trio of mischievous otters riding a hovering, iridescent seashell, while a regal, rainbow-plumed mermaid queen observes from a nearby throne, flanked by a stately, gemstone-encrusted sea dragon and a school of bioluminescent fish darting through the crystal-clear waters.
