Mishima Reika from RahXephon.
This is a really old picture [from 2005], and I decided I wanted to color it. See the line art here.
I kind of like how it turned out, because it's a little different than what I usually do. Although I wanted to try a different way of shading, I ended up staying with cell shading. =T
As for the background, it's actually a somewhat old thing I did when I learned how to create fire in PS. It just came to my head and I wondered how it would look as a background for Mishima, and it turns out it's pretty good. =D
