Here is why I think u should improve.. Remove the vid please refilm it and using the suggests that I'm gonna give u:
1.- When u are doing packet tricks where u have ''4 cards'' the camera should be up so we can see the thickness of the packet.. It seemed like u had like 10 cards.. the idea is to show 4 cards and make the spect. think that there ONLY 4 cards.
2.- You can practice more the ascanio spread and do it over and over again and you'll get it much SMOOTHER..
3.- Why on earth did u move ur hands towards you and start shaking the cards :S.. it should look natural shake it there don move your hand towards u it is weird, and it doesnt SEEM NATURAL..
4.- Practice, practice practice practice..
5.- It should look like u are just showing the 4 aces turning magically them over and then shake them turning the into the kings..
I'm almost sure that u didnt practice 20 minutes.. u watch the dvd or learned the effect and film it.. because u think it looks cool, rewatch the vid before uploading, watch the mistakes, if u cant watch the mistakes, the multiple cards then upload it.. those are my two cents.. refilm it and post it
peace
