This stunning illustration features the four Ninja Turtles - Leonardo, Donatello, Raphael, and Michelangelo - in all their anthropomorphic glory. With their masks and weapons, they stand resolute in their mission to protect their city from crime. To bring this dynamic image to life, hues of blues and greens should be used to depict their reptilian skin and shells, pops of yellow to represent their eye-masks, and neutral tones for the background to create a contrasting backdrop. Outline the edges of the turtles in black to emphasize their individual personalities, and include splashes of vibrant greens and yellows, in order to capture the intense energy of this heroic team.
