Edit: Just thought it was important to mention, I never really did any traditional art (seriously). I started digitally with that mushroom guy I posted below. I did like to draw Wario and the Noid a LOT back when I was in highschool, but that mostly boiled down to giving the noid huge boobs, or drawing Wario's face on popular characters like Kirby, Steven Universe, and whatever else was relevant in the mid 2010s.
This isn't anything that isn't on my profile, but the earlier posts on my page often looked something like this. Granted, it was literally my first time drawing, and I knew that they weren't good, I mostly uploaded them here on NG for archival purposes (Most of my old drawings from this time frame are gone, but most of them were more like "Angry Bean Guy" and not "Fancy Mushroom")
Fancy mushroom is honestly kind of crazy for my first (proper) digital drawing, it has it's issues, but it holds up better than all my other old pieces. I still like that dude to this day.
My more recent pieces are still not great, they lack important things like uh, backgrounds, perspectives, proper lighting, but there are some character design stuff that I like that's starting to show up in my little guys.
I'd have to attribute most of my recent art improvements with the development and release of my game's demo, Viva Hexagon! Feat. Ipulo, since I had a huge motivation to perfect/finalize the character design before I immortalized it by animating it (which in turn improved my other characters designs). Also, having a good character design made it easier to animate. I know NOTHING about animation (it was my first time), but Ipulo's (the bee guy) simple yet flexible design kinda hard carried the process.
