You know how you stop all the accompaniment during the chords in pattern rows 4 and 5 (the "DUNNN DUNNN DUNNN" bit)? I think it would be more dramatic if you only did that the last time. As it is, I think it takes the energy out of it.
Funky, I like it! However, there's something I can't really put my finger on about the "DUNN DUNN DUNN!" part. Especially once it goes on the third and fourth time. It does sound better without ALL of the accompaniment it had earlier, but it feels a tad off still.
Anyways, pretty neat stuff. I'd like to hear more from ya.
