Nice little beat.
Try experimenting with some more effects, it all sounds a little dry. Try using compression, distortion and reverb on the drums (not necessarily all at once), then try it on the instruments.
Also, without being harsh, it sounds like your not too practiced in composition skills. FL's piano roll means changing keys and making up new riffs is a cinch. Try dragging your blocks around for some variation on the riffs.
Just a little advice. Good work all the same!
