Hi EugeneSoh,
Good work on the video! However, as I watched there were a few minor things that I felt needed to be said.
First and foremost is (in my opinion) to go slower; make your movements more fluid. As they are right now, during the Biddle steal for example, you went far too fast. If I was your spectator, I would certainly feel something happened at that time -- especially since I am looking to make sure mine is there. If I, as a spectator, realize that there is for some reason an unnaturally fast-paced motion at a time like this, I will feel nothing but suspicion toward the performer. As a result, I feel if you take your time and go much slower, it will work out much better for you in the end.
Also, like someone else said, perhaps it would be a nicer idea to leave the four cards at the end separated from the deck. Thus, to further show how there was no manipulation involved, and to give the belief that the packet and the deck never really touched. Therefore rendering an impossible transposition when they were sure to Hell that the packet consisted of their card and four others. Psychology here is key for making the effect what it is.
Despite, I thought it was a rather good performance.
Keep it up,
Jordan
