Its good, but....
The beat definately has that dark d n b style to it, but it's not got enough variance to keep me interested for long, some simple high hats and some nice breakdowns might help that. There is also a serious need for a phat bass sound to be used as the track sounds too middle and high end at the mo. It's ok but it needs some proper tweaking and some more in yer face fx and samples to really get it jumpin. Also that sound that comes in during the middle section where there's no beat is a bit out of place. It could do with being arppegiated instead of just single stabs.
Hope thats not too much critisism. Just tryin to be constructive.
