Looks nice. However, as Mastermoo pointed out: he is leaning too much forward. Looks like he is gonna crack off at the knees. Usually (from what i can tell, anyway =P) when someone has used alot of energy and falls forward, they bend at the back and keep the knees mostly straight. However, here it seems to be like his back is straight and his knees are bent. Anyway, it is indeed a great animation. Tons better than what I can hope to do, at least =)
