Those are some really wonderful gestures!
Accept that your skill is always going to be a work in process, and don't think about how fast you improve. Different people grow at different rates, and you shouldn't compare your personal growth rate to others.
I deal with it by not really dwelling on it, but I had some studio major peers who bordered on emotional abuse with how they talked to me about my art and what I should be doing instead. I felt dead inside for nearly a year after I finally graduated and got away from it all, and I made almost no art at all because I'd pick up a pencil and immediately just feel like "why bother". I wish I didn't do that, because the more regularly I draw the better I get. I stopped for a year and that set me back, cause as soon as I stop drawing I actually go backwards pretty quickly, art for me anyway definitely is not like riding a bike lol.
I think one of the funnest things to do is to look back at slightly older art, it's almost always better than I felt about it when I left it. There's always some small parts that are good, even if the whole isn't so much.
