The only thing I can say about drumming is make it emphasize the piece, not simply to give it rhythm. The percussion work in here is fun to listen to so you're not having a problem in this track. When I'm making my tracks, I've started to make each percussion pattern unique so at the end I'm getting about 8-10 different percussion patterns, and it's not even including sound effects. But each one is different in some way to make the piece a little more fresh. I try to take special care in making the kicks and the snare hits kind of accent notes and rythyms with my synths instead of laying down a steady beat.
All-in-all, it's jammin'.
