I have to primarily say that your shuffle and false dealing work is first class skill. Having that said, I will have to point out that there are a few minor flaws your execution has. About the seconds, I think that you should have shown nonconsecutive seconds, too, and that you are putting just a bit too much pressure on the deck while dealing, so the deal misses that perfect naturalness. Having that said, too, I will point out that your timing is perfect, and the rythm is flawless. For the bottoms, the rythm has a tiny difference, and the card goes out from the deck just a bit different from the top deal. This is just my humble opinion and some ideas you might concider playing with, and if you want to, I can pm you over facebook, because we're friends there.
