Some interesting ideas here, not really mainstream dnb in sounds and melodies though.  The break loops contribute, but the bass and lead sounds and what they are playing aren't quite there.  The sub-bass (which sounds like a bass guitar) is just too regular and static for my liking.  Are you playing in a major key too?

On a production note, the lead is too loud and distorts a lot of the time but there are nice envelopes and swells on it though.  There is room for some more sounds to help the flow, like a crash cymbal on a breakdown and a drum roll before the rhythm kicks back in.
