I just got bored, so I wanted to try fixing someone's art :D Little tip for @MolotovBlue - So I think you should start with bases (aka sketch but I like calling them 'bases') if you want to draw cats. Like, start out with a little sketch, make it messy as long you can understand it. After that you should outline and edit the sketch with a different color that isn't the color that you used for the sketch. This way your art wouldn't look like a whole mess. Never try drawing something in one go, it can sometimes look worse than expected
