I'm going to second most of what everybody's already said.
You're awesome, in fact, as soon as I got back from Connecticon, I pulled your arrangement of Cruel Angel's Thesis off the web, and resolved to learn how to play it. I haven't succeeded quite yet, but, that's how it is.
Everything you arranged was rather fantastic, however... The only piece I really have a criticism on was Aeris' Theme. As I remember, it was one of the few or only pieces you didn't arrange. The performance of it was really beautiful... I just think that the arrangement was too, well... busy. Aeris' Theme has a simple beauty that the arrangement didn't quite capture, I think.
AMAZING performance though. Keep it up!
