Underwater world

Vibrant, iridescent underwater realm, teeming with exotic marine life, intricate architecture, and mystical glowing flora, set amidst a vast, dark blue abyss, illuminated by shimmering shafts of sunlight, with majestic, ethereal creatures soaring through the currents, in a highly detailed, 8k resolution matte painting, reminiscent of the fantasy concept art of Simon Stalenhag, Syd Mead, and Ash Thorp, with a deep, rich color palette, incorporating complementary hues of turquoise, emerald green, and sapphire blue, evoking the cutting-edge visuals of Unreal Engine 5, as if trending on Artstation.
