i like it. but your explosion was lacking. i think you should have used like a trailing effect when the head was spinning around. to sort of help show the speed.
but thats good.
easytoon, i think takes more skill. and i personally like the results much better too. its way more, like allows you to do what ever you want.
pivots good too, but its kind of i dont know like 'move this joint, then this joint then this joint'
but thats just my thoughts.
