If, for once, you will acknowledge my advice, I shall give it to you. In fact, I shall anyway
It seems to me that you've learnt a trick, or several, and once you understand the mechanics, have video'd them. Not only do you have to have the mechanical side of the performance perfect, but also the presentation and handling. You handled the cards clunkily and without certainty. Make your moves smoove and gracious, both will come by continuous practise of the effects!
For the second time, buy a book like Strong Magic by Ortiz or The Performance Of Close Up Magic by Eugene Burger and learn how to properly present your effects.
Keep up the Magic eitherway!
