Real Decap: Really nice punch, it had a good fluid motion and look pretty powerful. I liked it.
Head Smash: Definitely the better of the two. Nice use of uke to gain momentum for the decap. Pose was good to. But like, the second kick didn't do anything :<
You should edit that second replay and make something of that other kick, would be an awesome. Oh and relax more, you get +style points from the pros ;P
