This Monsters versus Aliens coloring page is definitely a thrilling one! The alien is huge, with multiple eyes and sharp teeth. It stares down menacingly at the much smaller, terrified human. The human has bright blonde hair and a blue shirt with a white collar. It looks like the poor person is about to become the alien's next meal. To make the image even more dramatic, try coloring the alien in a dark green or blue, with a bright yellow or orange for the eyes. For the human, use something brighter and more vibrant, like a pink or yellow shirt, and shades of brown or gray for the hair. Finally, to bring the whole scene together, use a darker color like black or navy blue to outline the scene and make it pop!
