Nice one
Loved it! Suggestions, well...
-Maybe even smoother animation for walking? He still moves a bit odd
-Maybe change the way he looks a little? Give him some attitude, I'm not sure about the way he leans back like that.
-Clips flying out the gun. You know you want to.
Ah, heck. This is brilliant as it is, forget I said anything. :) Can't wait for this!
