Thanks, everyone. :]
I still have a ways to go, haha. Particularly in color and AAing; I seem to struggle there.
@Luyren: Yeah, the lineart I can't change because I want to keep the spirit of the challenge in there, but the shading is a bit wonky.
@Greg: Thanks man!
@thebigdooz: Thanks! There is definitely room for improvement, I feel.
