I've been too far removed from the Jr.'s program for my insight to be valuable to you, but I'll toss in my two cents anyways.
:26 Don't put the card back onto the deck top unless it's for a purpose. IE top change. It looks suspicious.
:28 Why are you fanning? Stop that. There is no reason to fan at this point.
:51 Slow down. I barely got a chance to see the second Ace. I know it's spades because I spend the majority of my days looking at a deck of cards, a normal mark may not be as quick.
1:02 Three card monte? Two card monte? What the heck is a three card monte, or a two card monte? Your general audience, usually being non magicians won't get this reference. Don't use it, lose it, and find some other way to illustrate your point.
1:31 I'm not pretty confused, I'm pretty unamused. I've seen nothing to support your claims that the cards are changing places. The first change exchange is fine, but the multiple taps is over kill- unless you plan to show at various intervals that changes are actually taking place.
1:36 Quit fanning. Thats magical masturbation; done because it only makes you feel good, and serves no greater purpose.
1:49 Fan. fail. knock it off already.
3:45 You talk about palming it into the deck box. Why? A spectator isn't going to know what palming is. Cut that line.
Overall you have no script or patter. You're doing nothing but talking me through your actions, which I can clearly see. Audience members aren't stupid, and you're a magician, not a cooking show host. I'm going to take the nine, have it signed, put it back, shuffle...etc. By actually scripting out a patter, and rehearsing using that script I think you'll tighten up the routine quite a bit.
Slow down, as it's been said, don't rush things. Take time to understand where the magic is, and why it's magical. Don't just blaze through it so you can get to your next double lift.
all the best to you in March.
