Wonderful.
I reckon that if you delayed the tie a little more, it would give the animation a bit more flow as it is currently in synch with his right leg. Also because the body and legs are so smoothly animated, this makes the actual head of the character feels a little less animated. You could have the head move side to side slightly.
Decent animation though some parts bug me a bit (probably personal preference). Also you've got some unwanted transparent pixels in some places (they show up clearer cos I'm not using the defaut theme)
Love this animation, and the guy's expression. So awesome!
