To tell you the truth, that's a really nice sprite to make while drunk.
Yes, that is certainly much more Bison like. I just think that you didn't have to remove the little shading near his mouth (on the third sprite), because it actually looked pretty decent and fitting to him.
Nice detail on the face, looks pretty original! Btw, you can take my old KFM avatar on the first post if you want.
Do you still have a place in your heart for making more? You did a great job with the KFM portrait.
Also, funny that you added Reiji. When I first saw your avatar, I actaully couldn't help but to think of how similar the guy looked to Reiji himself, hahah.
