We all have our moments where our creativity can be overshadowed by the need for perfection, and though it may be hard, you have to let go. You have to embrace the imperfections. Drawing without concentrating on it needing to be perfect is very refreshing. Instead of going over it and sketching it, just try snoopy, fun lines. Drawing should be fun, same with animation. You just have to learn to let go of worry, and draw with full force. It’s a bit hard to explain, hah. But I gotta say, I'm still working on that myself. Refrences help, studying and analyzing how the lines work on what you're trying to draw helps to. One day you'll reach a point where you won't always hate your art. I've reached that point, but I still have much to learn so not quite! I wish you luck on your journey! ♥️
