I smell Vocodex at the start. Drums need to be boosted definitely. Or perhaps your other sounds reduced, because I can't feel their full potential. They should be the driving force i assume - as it's called Drum N Bass. The mix sounds full though which is good. Not empty. Your use of the vocals was great to listen too though. At 2:37 when all the sounds kicked in I detected some SLIGHT clipping. Your bass line though as lovely and thick - i liked the portemento you used as it glided from one note to another. Overall, it was well done. Good stuff mate!

Great job. While listening I actually made a theme that can be animated on this music.
