Well, if you want me to remove this reply I will. This is my honest opinion.
To me, this performance is too revealing to the spectator. I personally would just guess that you laced a rubber band through a portion of the deck, and tied it to a platform to support a given card. I don't claim this to be the solution, and I won't even be surprised if it is not, but the point is that almost any spectator will know that you used a gimmick. The way the cards are bunched up as you spread them is very suspicious. In addition, when you turn the deck sideways there is a gap that shows. I am suspicious that the end of a rubber band is making the break occur. Again, if you want this reply removed, I will.
I do see potential for this type of performance. Try to make the spread natural. Don't flash breaks. The way the card reveals itself is nice. It just needs to be better concealed....
