The man is standing with his hands on the glass of the aquarium, looking intently into the water. Inside the aquarium, vibrant orange, blue, and green fish swim around, amidst the swaying plants. He seems to be captivated by the beauty of the creatures and their environment. To add to the scene, color in the man's clothing a bright yellow and the background a serene light blue. Meanwhile, fill in the fish with shades of blues and greens, along with the aquatic plants in a soft shade of yellow. Use slightly darker colors for the outlines of the man and fish to create a contrast to the light colors of the aquarium and its inhabitants. As you finish, you'll be able to admire the awe-inspiring beauty of the man and the peaceful aquarium he has before him.
