Second, there was way too much thumb action. I think you may be performing it incorrectly in that way. The fade was too long as well. Otherwise, it was fluid and smooth, which is what counts.
I would try turning your deck hand to be more open.
The last thing is something to think about "The difference between a magician and a gambler practicing is the magician will deal in a pile, the gambler will deal hand." What good is this if you can't deal hands?
