World Expo 2k6 Tour Shirt

This is a t-shirt design that I created for work. The "concept" was supposed to be a rock/concert feel. I'm pretty sure that I accomplished this, but I am looking for feedback. Everything in the design corresponds to something that will be taking place at the expo, so if something looks odd (like the Temptations) I had to put them in. There were certain design elements that needed to be included.
