Very interesting. The first thing I would have to say is that I wouldn't call this drum and bass. Or if it is, then it is a certain style of DnB I am ignorant of.
Personally, I couldn't see myself listening to this as music by itself, but as background music for a game this would would create a good atmosphere. This was meant to be slightly a-tonal correct? Although it does have a 3-chord progression, the bass and drums make it sound kind of tune-less. I don't know quite what you were going for but... It's interesting.
BTW I reviewed, rated and downloaded your track, "Dancing In The Dark" and it is now sitting quietly in my iPod :)
