well first of all not showing a trick or doing a move twice is exactly what your suppose to do. :) if u have a real quick trick try to perform a better / bit longer trick afterwords works for me. xD
i like the way you hold your cards very light touch... but yes i think it was a bit too long for the same thing to happen but still very nice i liked it.
there is a lot of good information here.if you are still new to performing for strangers you can start a trick that does have them pick a card... thats what i do normally
the winning post is a good idea of what David Blaine does for me and many other people. :)
on a side note congrats to the winner and today is also my birthday!
Happy Birthday David Blaine!
