Music Festival Poster Concept

I came up with a quick music festival poster concept today. Won't be touching this up any further because it won't be used.

Just thought I'd throw it out here because I'm quite happy with how it turned out considering it was put together in 5 minutes. Please pardon the typo on the right and the sloppy masking on the guitar.

Would love some comments on how this could be improved or if you'd like to do a rebound, that'd be even better! (:
