Only watched it once, and I'll probably send you a more detailed PM about it with more in depth critique, overall it was good.
The first effect (well mentalist call the first effect 'you') was great. You introduced yourself, got everyone clapping and let them know it's okay to clap and have a good time; at the same time you established that you weren't trying to fool them just to trick them. I think the applause either way starting things off very well and everyone now knows that this is going to be relaxed.
The cards across, though slightly rushed, was done really well. I prefer two spectators hand to hand, BUT that's neither here nor there as everyone enjoyed it.
Doc Daley's Trick was performed very well, Alfie was right when he said it seemed a bit muttered throughout, but that's too much of a problem.
The biddle trick didn't seem to flow, not because of the pauses, but you said it was about 'estimation' and then had a volunteer pick out cards, I think it can be overhauled and tweaked to flow better either presentation or handling-wise.
Carbon Paper was very good. The only problem I had with it was blocking, I could tell you're used to performing for smaller groups, but if you would have turned your body so that everyone to the right could have watched you burn the card it would have opened and invited everyone in. The script for this one could also be refined, it just seemed meh (compared to the potential).
ID. Overall it was great, the selection did seem rushed, that wasn't entirely your fault but it didn't hurt the effect any. I have a few lines I'll send you in the PM that'll help build it and make it play better without changing anything. Also, for that big of a group it's almost better to do the fan at chest height with the back of the cards facing you and the display showing to everyone (I think we talked about this though.)
Anyway, I'm going to watch it again tomorrow and then PM you some better (more in depth) advice. Overall it was a good performance, and if the second one ended up better than the first then kudos. Almost everything I'm going to end up PMing you are things that would work themselves out through regular performing for this sized group.
