Looking good

Your cheat setup needs some work but it will come naturally if you keep practicing, besides that the first thing i noticed was how extended your abs were, not only does it take away from the cleanliness of the trick, but it also takes away from the power of the kicks, you want to be kicking that shit like an asian mom who found out her son got a B+. Also you should always extend your ankles(refer to my usertitle), in real life, you don't want to be kicking people with your toes, that would most likely break them.

Besides that stuff, this was a very good jackknife, try some more and see if you can improve and refine your technique.
