I agree with Dan; there's an awful lot of hissing up there that could be way more pleasant with, perhaps, the judicious use of a gate? Might be worth experimenting with a de-esser, perhaps. That breakbeat sample also makes the groove of the track feel a bit awkward. If you're not already, maybe try pulling it into ReCycle and experimenting with swing a bit, see how that changes the feel of the track. Definitely need to get rid of some or all of that hiss - maybe an autofilter?

Good solid TR-909 kick going on tho; I bet this sounds great on a PA.

I especially like the weird loop that comes in at about 1:30 and again at about 4:55. :) The kick breakdown at 1:52 seems a bit out of place (on the wrong bar, perhaps?), but is definitely welcome - I was hoping to hear more kick fills like that later in the song, say, every 64 bars. :) (I LOVE REVERSE 909 KICKS)
