@ChloeGreenbergArt When you're doing art for fun/personal, you have to be comfortable with making ugly art. If it's for fun, it doesn't matter what the end result is like. The expectation of having to make something that looks good is what is paralyzing you. When experimenting, there's no way to know if it'll turn out good - it's an experiment. If you fear making ugly art, you can't let loose enough to try it.
So sit down with the goal of making something ugly! Like... grab some Crayola markers and the ugliest color palette you can muster, and draw with that. Full expectation that it will look bad. And just have fun!
