I saw a topic like this a long time ago, but I can't seem to find it anymore, so I figured I'd start out a new one. Anyway, show me your art improvement!! For example! I did a redraw of a drawing I've done twice, and I plan on doing a redraw of this specific drawing every year for a while. It's fun to see!! Plus, I think it really helps improve your own self opinion on your art whenever you feel like you're in a rut, or not improving at all. You'd be surprised. (I know I was.)
Here's mine for you. (Even though, Oh god, those first two are so scary. haha. Gotta start somewhere!)
