Love this, but I agree with Evilagram. Fewer frames mid-swing would give the action more realism

Needs wider spacing mid-swing.

 So nice... i want to play this game!

It's a bit slow; otherwise, not bad!

cool but maybe seems slow?

 LOL, I love it, it's so smooth.

Wonderful animation! I really love your styple!

I like the other one more, this one doesn't look like it has much force to it. Still great.

 Nice animation

Excellent!

Very effective.

Very nice.  I love stuff like this.  Lil sprites that aren't overly cute or anything but smoothly animated and well pixelled.
