It's got some really basic synths, but some pretty interesting melodies. The main problem is the gain. You've got distortion coming through when you have a lot of instruments playing; probably because you're cranking the levels on some of the lower frequency instruments to try and compensate for the amount that the higher pitched instruments take away from the bass.
It's a fairly simple thing to fix by using EQs rather than just simply adjusting the faders. If you'd like some good tips on how to mix with EQs rather than simply cranking your levels, toss me an email or PM and let me know what program you're using primarily. I'll let you know what kind of EQ plugins I generally use and simple little tricks to make your instruments mesh better together.
