I'd actually be more concerned if you weren't getting any better. The more you do something, the better you usually get at it. This is true for art, writing, basically any hobby or profession. Sure some people have that raw talent where they're amazing right out of the gate and don't need any practice, and that quality stays with them forever. But for most of us we improve as we grow.
I don't really consider myself an artist despite going to art school for a computer arts degree. Drawing is something I struggle with because I have to see it to draw it, I can't draw what's in my head. But my favorite story from art school, and the reason I'm mentioning this LOL, is a real life drawing class I had made my professor do a back pat for himself. Our very first project was a self portrait. We had to draw ourselves. To say I hated that project would be an understatement because I really have self esteem issues so drawing myself was horrible and the art reflected that. It. Was. Bad. I think my professor honestly thought "WTF is this chick in art school?" (because I like graphic design and I'm good at it...as long as it doesn't involve drawing LOL)
Well the semester went along and I had hits and misses as I had to keep drawing, but the last assignment was we could draw anyone we wanted, but it had to be a person. So I picked this picture of my mom that's my favorite picture of her right before she died. I drew that. We had to bring in the last assignment and the one we thought was our worst. I obviously picked my self portrait as my worst. My professor looked at both of them and said to the class "See, anyone can improve. If a student had gone from this * points to my mom drawing * to this * points to my first drawing * I'd quit teaching right now." He was proud at how I'd improved.
So the moral of that story nobody asked for was that the more I drew, the better I was. I still couldn't draw anything unless I could see it first, but I actually created drawings that were good. Now that I've been out of school for years and don't really get to use my degree I'm back to barely being able to draw a stick figure, but if I got back on the horse I have no doubt I'd improve again.
Be proud of your improvement. Enjoy it. It means you're doing it right.
