Wow! that is a complete turn around from your first version. Sorry to be a drag, but I think now its gone too far the other way. The information is hard to read and too small so the main point of the poster is lost. As much as it is nice to use stylish images and effects dont forget the primary aim of the poster is to promote the event so that message should be easy to read and understand at a glance.
thats better matt. when ive done posters for gigs in the past Ive been told who the headline band is so Id check to make sure Part Chimp are the major players for that night otherwise it wouldnt make sense to base the whole concept around them.
this is purely my opinion but I actually prefer the original poster. I understand you wanted to try something new and its obvious you have been heavily influenced by the tutorial above but for clarity and style I prefer the first version. I think posters need to be clear and concise, they only grab peoples attention for a matter of seconds so if there is too much going on then the message will get lost.
Like Berry said, design is about communication, not aesthetics.Its crucial that your message is first and foremost in your design.
Learnt some nice tricks and shortcuts from doing the tutorial, but yes i agree, i prefer the original design, i have this poster on my wall at home - PART CHIMP | Flickr - Photo Sharing! and was trying to think bold colours, big graphics etc.
