Unrealistic Colors

So obviously, this portrait that I made of my friend is not realistic in color. At least I’d like to think that he doesn’t have purple skin and red-purple hair. Doing stuff that is unordinary is rarely ever looked down on in the art industry. But, I am definitely not the first person to ever do this. I find it easier to do unrealistic colors because you don’t have to worry about if the skin color makes them look sick or like a peach.
