First of all, you are very very stiff. All the way through. You need to relax more, so you can get a nice flow going. Also, I must remind you, that it's not only about dismembering. A replay with an awesome split or decap, is often better than a madman with no style.
Also, next time, make a decent pose, and dont ruin the pose you already made.
Try practicing in single-player for some weeks, and then come back. I'll be happy to give you feedback again. Anyways, 2.5/10 for this time.
