I agree with the above post in that you seemed juuuust a bit to fancy with your presence in very casual setting. Your patter was nice and clearly rehearsed since you didn't stumble, which is good.
IR: I've seen that card tab thing before on youtube, and the other guy did a better job of explaining the whole illusion thing in my opinion.
http://www.youtube.com/watch?v=MYOq0XWR25M I do like how you made adjustments to the last time you performed this and didn't let them hold the box before the reveal, I could tell that created a much stronger impact when the block just appears. I do agree with less is more, you penetrated it a few too many times. Do the card tab, then let someone stab the knife through, then reveal. Boom.
Voodoo doll: Same as above, too much up and down and up and down and up and down. At first it got good reactions, then they just started to dwindle. Let him raise it and lower it, then raise it one more time, then make it fall with the finger snap.
Ace location. I skipped it because it bored me, sorry.
Snowstorm was awesome, I've never seen it before and I loved it. A few things though. 1. After a spectator shuffles, no need to say "they are mixed up now right?" Of course they are mixed up, they just shuffled the deck. That kind of phrase is totally pointless. 2. "A regular sharpie, yeah?" Again, why say this? Of course it's normal, they don't know about trick sharpies, so don't lead them in that direction. You are starting to run when no one is chasing you. 3. You over-proved the drawing wouldn't move when you rubbed it. Again, of course it won't move! Blow on it, and rub it. If they don't see a smear, then the drawing is intact, that's what we are accustomed to seeing so there is no reason to over-prove something so obvious. You asked if it wasn't magnetic?? Why? That's such an illogical solution for someone to come up with there is no reason to even bring it up just to cross it out. One quick rub to show it's dry and you're golden, period.
The last effect was waayyyy too long. Again, you're over proving something that doesn't need it. If a spectator shuffles the cards, they are not going to think there is a stack involved because it was them who shuffled it.
Not trying to rant at you, but it's just little things like that that make me cringe because it's so superfluous. The main things to take away from this are less is more and don't run if you're not being chased.
Other than that they all seemed to have a great time and you did perform everything pretty well. Good job and props on doing live magic!
