The opener itself is fine but you fully contract your left knee when going for the scoot, there was also a fast extension of your left knee after it had hit the ground. Right after that swing through and air stuff was finished there you had another rapid knee extension of your right knee this time. Then after the sailor moon -> flash kick you did I was completely expecting a cork, or a cork variant but instead you did this weird hand spin thing that I don't know the name of, this actually looks fine, but it seems like you did it as a cork substitute. Your neck stayed in the extended position throughout the whole flash kick into hand spin into the cork. Speaking of that cork I think you untucked too fast making the spin look slower than it actually is, or maybe it's actually slow? Not sure on that one. Another around frame 500 RKE (rapid knee extension) ANNNND the rest of it looks fine to me.

In conclusion you suffer from RKE! This is an easy fix! just take your time!!

idk why you asked me to cnc if im worse than you lol
