The move itself is performed well, although I've got a couple of suggestions. First, I think the angle you're filming from is slightly unnatural. If the camera was a bit higher, looking down from eye level, it would give us a better idea of how the shift would look in a real-life situation. Also, I think you could tighten up getting into and out of the move. I don't feel like you justified turning the deck to get into position for the shift, and the move didn't flow into the squaring action at the end. As Erdnase says, the hand positions should be taken with "easy deliberation", which I think you're slightly missing at the moment. I'm sure you've thought of those points already, though, and I look forward to seeing how your shifting progresses!
Oh, and I definitely agree with keeping the "hands stationary" (to quote Erdnase) as opposed to the up-and-down covering action.
