You need to practice a lot more to smooth out your actions. You had two MAJOR flashes that might as well expose the effect.
The core of the problem???
You are going WAY too fast. Slow down bro, you have plenty of time. Slow down when you practice, slow down when you perform, just slow and smooth and easy, nice, calm breaths.
Now that you have your criticism, I recommend you take your video down and come back with a better one. : )
