Pretty cool. I like the mohawk thing on the first one. I was thinking of making a really fast enemy type that runs around you. If I do you've convinced me that it needs a mohawk. :P
Btw, you can embed the images by pressing the <> icon up top and typing <img src="yoururl" />
It's an interesting take on armor. It might be kindof cool to do something that sticks out to the sides rather than just in front. As you may have noticed the horizontal swing is super powerful right now. If there was armor that blocked horizontal strikes (and shattered when you hit it) I think that would be interesting.
