the hand is way off in realism. it looks like one of those fish fists from spongebob squarepants!

but work on the realism on the fist.
another point which could really be fixed is the thing that is breaking. it doesn;t look like its being shattered by a fist, but broken in half by a karate chop.
It will seriously look good after that.
Btw, wouldn't his hand get sliced down the middle if he punched down the middle of the sword? XD
its a 2/5 from me atm. but keep trying.
