I had seen Prezi mentioned once before here on VAF and played around with it a bit at that time, but haven't had the opportunity (er... extra time!) to really work with it. I will say that I LOVE the way it works, the way it looks - it's very cool.
I watched the first portion of yours and quite liked it, though I might recommend including text on every frame. There was at least one frame with an image and no content... Just for the sake of your busy potential clients

Great job!
(And thanks for the reminder about Prezi, I'm going to take another look

)
