I might as well give some CnC. I'm not seeing very proper or truthful responses.

Spinning kick: Well, it has potential. I'll assure you that. Opener looked nice, kick wasn't too good, and the boomhit was.... eh, just a boomhit. To be honest, it wasn't much of a kick. It was more of a leg choke. Try the same opener, but use a kick in between the arms and neck area. 5/10. Keep trying bro.

Tumble Roll: Err... Not sure what I was really... looking at. Walk was.... okay, I suppose. Not sure how to help you with that one... All I can give it is a 3/10. Yet again, keep trying. Maybe attempt a better walk and simply decap him. You know, nirs style.
