The line up to the first hit was smooth and stylish, but you could get a better boom there. Just aim higher or go for a diffenent approach, and do a single core.
After the initial hit, you contracted your knee too fast and it looked unstylish, try to be more relaxed ( this applies for all, if you don't use a joint then make sure it ain't stiff)
The boom hit after that was great, the aim was perfect. But avoid lowering your arm and then raising it like that ( the ungrabbed arm), because it doesn't look good.
The torso dm was unexpected, but I loved it and how it flowed towards the nice pose.
Oh and as another advice: use shift+p a lot if you have to. Especially if it will help you unstiffen :]
