About the effect "revolution", when you bring your right hand to take the coin on left, you should actually put all your mind on taking that coin with your right fingers. Also your tumb should get in sight ahead of your index as soon as possible without any fast movements.
You should never allow your right thumb to fall behind your left hand. Since this effect allow you to show all of your right fingers on the back of the left hand, you should do it.
I liked all the idea you've put to work on this video and your technic wasnt bad, just this details i mentionned would make it look a lot better.
Its just like a french drop, you must believe yourself when you take the coin between your fingers and everyone else will follow you.
Edit: After looking the video a couple times, i thought that you should experiment with a classic palm for the coin change and just wave your right hand over the coin. I will give it a try anyway i really liked the idea of a change using revolution.
Ill cut it there, i dont want to get into too much exposure
