Artistically, I would say you did very well capturing the spirit of the show. To me, the images say "Wishes!" and make me wish I were there now.
Technically, there is some image blur, probably from handholding the camera for maybe 1/4 second. If it is a SLR you can crank up the ISO. If you have a P&S, not much you can do other than carry a tripod, which is a bother. Or use a "treepod", "trashpod", etc.
Overall, I think ya' done good!
