If I had to give that a number (which I rarely do) 2/10. Seriously, that run you got off a youtube tut, and the decap, you had to rely on gravity to decap him. Running gives you quite a bit of momentum. You definitely could've gotten the decap in just one hit instead of pushing Uke to the floor. But then again your only just a beginning.
Keep it up though. You'll get better in time. Don't let this discourage you. Just try to make your own stuff.
I have no replay though. If you like, you can comment on some of the replays
