Well done! Good reactions too! I think you could have incorporated the spectators that came to watch you (that family of 3) to make the magic more powerful as well, but that's the only feedback I've got.
Keep up the good work,
The biddle trick i think you sold short.
The biddle trick comprises of 3 effects and you didnt really get the full potential out of all of them.
First you are able to divine their card (which you didnt do) then you cause the card to vanish, finally you cause the card to appear reversed in the deck. You need to separate and clearly define each phase to really get the most out of this effect.
Jon Armstrong has some nice thoughts on this in his lecture.
Its always refreshing to see a live performance video, good job.
