ill get right ito it:
first backflip looked slow and wierd, not the best.
your try on a flash kick wasnt that good, it worked but you could have improved on stability a little bit more.
cork itself was great but it would have been good if you got a little higher up while doing it. also. pls dont cork to the side, it looks a bit wierd, go backwards instead.
pose was great, i didnt see any flaws with it.

overall: 7/10
