These were done in 2006 as I was learning Painter IX. (I realize now I've already posted them on this site, but that was years ago). I found trying to do a new concept and come to grips with a new program's workflow and personality was counterproductive, so I ended up just painting some favorite old Quake characters with minor changes to their designs along the way.
The Mynx picture is previously unreleased; I was always intending on finishing it but it looks just fine to me now. Bonus sketch included.
(Full disclosure: Sorlag is not a favorite character.)
