(2007, anime attempt 1) Before I had my own computer, I liked anime, but wasn't able to watch much of it, so I was going off of vague recollections of spiky hair, sparkly eyes, and a few stock facial expressions. I drew a lot before this, but those pictures are lost.

(2012, more cartoony) Around here is when I started using the internet to find art resources and learned the fundamentals of art. (Technically before that, but those pictures are sadly also lost.) I was also exposed to a lot of artists through deviantArt and later other social media and wanted to copy what they did. This led to a lot of experimentation where I eventually started to discover that I liked bright colors and expressive features. In this period, I branched out beyond anime.
(2013, idk what was going on here) I got hooked on a lineless style at some point. This worked for when I was doing Sonic fanart and drawing in Microsoft Paint, but soon after creating my original characters, I realized that a lineless style might not work as well for these new designs.
(2014, current style trajectory) Then I discovered the artist of this picture, whose style encapsulated pretty much everything I wanted mine to be.
(2017) As much as I wanted to copy that artist's style wholesale, there were other styles that caught my eye, so I studied a bunch, picking and choosing what I wanted to incorporate into my own.
(2022) That pretty much leads to where I am now.
