I drew before I could write, scribbles in class, random comics here and there, but I didn't really think 'wait I think I should practice and turn it into a thing' until I was about...20 or so when I realized my degree choices weren't for me. I wish I had taken it more seriously at a younger age, but with constant practice, hard work, and accepting suggestions, I think I've done some good leaps in improving.
Like a lot of people have said though, I look back at the things I drew just last year and cringe, and I think next year I'll cringe as well at what I'm drawing now. Hahaha...
I consider myself pretty decent just from a few months ago, tbh.
