I think you mean Boom-Hit?
A Boom is actually 3 Dismemberment's at once. You only got two. (Just to let you know)
Your movements seem very random and not thought out in advance.
Before you make a replay, try to plan what you want it to look like.
Like, say to yourself, "Hmmm, I want to push off the ground, do a 360spin, then decap Uke"
Planning out your replays helps I lot, I think.
~Good luck!
