Fantasy art concept. An ethereal handsome man. Set in an underwater realm.

In the depths of an underwater realm, a captivatingly handsome ethereal man with flowing, iridescent turquoise hair and piercing sapphire eyes, surrounded by an aura of luminescent seashells, glows softly amidst an intricate cityscape of coral and glittering crystal spires, as if crafted by the finest artisans of Atlantis. His elegant, silken attire shimmers with a mix of rose-gold and oceanic hues, reflecting the shimmering ocean's surface above. Inspired by the imaginative styles of Ruan Jia and Danny Gardner, with a dash of Mike Mignola's dark surrealism, this fantasy concept art piece is a meticulously crafted, 8k resolution, matte-painted splash screen, bursting with vibrant, complementary colors, evoking the mystique of a cutting-edge Unreal Engine 5 creation, worthy of trending on Artstation.
