A vibrant koi fish, painted in shades of orange and white, sweeps gracefully through a lush underwater landscape, its scales glistening under the sea’s surface. The fish is equipped with long flowing fins and big round eyes that provide it with a striking, expressive quality akin to characters found in children’s books. The surrounding scene is alive with bright, colorful coral reefs and tall seagrass plants, meticulously depicted in a realistic style that captures the fine scales and fluttering movement of the fish amidst the deep blue backdrop. This illustration incorporates elements reminiscent of artists like Kestutis Kasparavicius, showcasing bold, vibrant colors and simple, flat designs, offering high contrast that enhances the dreamy, idyllic underwater setting. This detailed design approach aligns perfectly with MidJourney style reference tips for beginners, who aim to create compelling, picturesque scenes that are both vibrant and engaging.
