One thing to work on is you move around waaaaaay to much, and I'm not talking about walking to get something. To a spectator, it's confusing enough to keep track of what's going on, and even harder when the magician is always moving around. Stand still and don't move so often. Another thing to work on is shuffling the deck in your hands and not using the floor. The constant up and down can be quite distracting, not to mention weaken the effect if done too often.
Thirdly, if you're doing a trick that uses a drink, make sure you're performing in a room with plenty of drinks to chose from. I don't know if it's me being picky, but that definitely didn't enhance the trick by any means.
Not trying to be a dick, as it wasn't the worst I've seen, but definitely not the best.
Good Luck,
Steve
