This is Josh

Pretty good. Some thoughts:
-Could use more of an introduction and conclusion
-Sometimes the guitar thingy overpowers everything else, so maybe it could be turned down a bit
-Try to include transitions between each part, it's kinda weird when everything just cuts off or suddenly comes in
-I guess some more variety of instruments would be good, so that it's not just the same things in different combinations
-That's all I can think of, but I'm not an expert. Try requesting reviews here: http://www.newgrounds.com/bbs/topic/1 072042
