Good start but...
I agree with Superstrings, this song has great potential, but to me it lacked a climax. As a matter of fact, I think it'd fit better under ambient better than Drum 'n Bass. The whole time I was expecting some spectacular climax where the drums finally stole the show and there was some kind of catchy hook behind it but that never happened. Decent song either way though, but I wish you weren't done with it. You put some kind of climax in there and this would be amazing.
