good start
i can see that you have a pretty decent idea, but you never really go anywhere with it. at the beginning it works, but after about 20 or 25 seconds, it starts wearing thin. perhaps a louder, heavier drum beat after then. i concur with another in saying that the eventual introduction of a more stern sound, perhaps trumpet-like, to come in with a very simple melody, with a heavier, deeper bass then. just my thoughts, you can really do something with this here, just keep at it.
