Hmmmm...
The bass notes down go together half the time. They are conflicting and sound offtune. Bad chords, I believe. A couple examples would be at 00:07 and 00:09. Unless it's just my ears or a ton of distortion from the bass being to loud, there is something wrong there.
And the beat sounds like it's in a bandpass the whole time. The beat itself isn't bad, but the sounds used just sound not full, when they probably should fill more of the spectrum.
I was hoping for more than a bass and drums as well, and some more variation on either the beat or song arrangement (the beat plays basicly the entire song for example, no downtime).
So, that's my few cents. Hope it helps.
