Congratulations are in order!
Though as too a Marvel vs. Capcom fan, I find this pose for Ryu pretty awkward since to me it would fit so much better for Chun-li.
The style itself is superb though, which I love about it. This would be great cover art, and I would definitely want to see something like this being used somewhere in a collector's edition of Marvel vs. Capcom OR as a cover for a Marvel vs. Capcom comic book! Did one ever get made? No? Well Why hasn't it! That cross-over would revitalize my comic book collecting ways.
Anyways, I'd like to see another fight between the two. I see where you were going with this one since Ryu does indeed shove his big naked foot in your face and it hurts big time when he does. I bet the same kind of impact would be seen if you had Ryu set with his patented haymaker with Captain America looking like he's about to throw his shield upside Ryu's face. Now that would be a pretty challenging drawing to test your skills on.
