So, yeah, it's been a bit longer than I would have liked, but here's another "in-progress" for the shockboxer. Color flats with a little bit of shading work. I ended up making his head a little bigger since he was looking just a bit ridiculous, but like where it's at now, even if it is a little exaggerated (or a lot).
First update on the boxer. I'm doubting that the original requester is still around to get feedback from, but hey, you never know.
