Hey that ninja is pretty cool. Seams like you have little problem with the shoulders rig. Hard to see exactly whats going on there but something looks fishy.

I think you managed to capture his personality realy well.

Hope you will pull of the slice animation as well. I little sugestion on that one if you don't already know how to do. Use a diffrent model for the slice animation were you have sliced him up and added the polygons in the slice then make a special rig for this animation wich is split in two. Hope this makes sense.

Whats the polycount on him?

You have chosen the most difficult and probably one of the absoltue most important one. I wish you good luck on it.
