I've got to agree with most of what is said about condensing it. There's also a serious lack of depth to the music, and there would usually be a bigger build towards either something more resonant or complex. The tempo was actually nice in the beginning and basically would of set the melody for something else...
The main problem is, there never was something else, so it's just one long, drawn out melody. I read up a bit when I was working on composing music for my games and found you rarely need to go over one minute. The best loops were a minute or less, so I've used that as a good standard. Yes, even 30 seconds in length would be quite acceptable.
I highly suggest checking the link below, it's a FAQ for Music Generator 2 and has some very nice stuff on music theory that can be useful as a guide.
