Awww, I'm glad I was able to help someone! :'D This made me feel pretty good, actually.
I think the best piece of advice I've gotten and continue to get to this day is advice from my animation instructor:
Art teacher: "What the fuck is that? It's fucking awful. Do better."
Me: "Fuck off, I'm trying D:<"
Yeah, doesn't sound very constructive, but just "Do better" is enough incentive for me to, well, do better. Having someone taunt you and then tell you to do better works wonders if you have the mindset for it. But you really do have to have the mindset for it; others would probably just be offended or feel put down by it, haha.
