I think if I had more artwork to show off, I would be splitting this directory into little subpages, but I don't. So for now, everything is in one page. Yay for convenience!
You can also view these artworks within the character directory! If there's anything specific you'd like to know about these artworks, check out the character page it belongs to, because I sure as hell ain't writing descriptions twice.
The sorting order here is: references and tutorials first, then whatever else.
