Here's some old art of mine from 2009 before I owned markers:
Fast forward to some Pokemon fanart from 2014 when I had some experience with markers:
Then some more recent art from this year, 2019, and probably one of my best marker pieces to date:
And a more recent watercolor piece of mine from May this year that I'm still relatively proud of, even though when I made it, I was still relatively new to watercolors (in fact I think I regressed a bit since then, so I need to try to get back to where I was):
I'd like to say I improved enough considering how there was a big gap in my life where I pretty much never drew for several years until recently, but I'm trying my best to improve more now!
