Needs work all around.
Drum and bass is all about, well, the drums and bass. Right now it's all highs. Where's the intricate bassline DnB is known for? Where's the spliced breaks? Listen to some Noisia, Spor, old Pendulum, etc. for inspiration.
Mastering-wise, this needs work as well. The drums are WAY too loud in the mix - they're clipping and distorting the other sounds you have going. Turn them all down. Turn EVERYTHING down before the compressor/limiter you have on the master bus. You'll find that everything will sound a lot clearer.
This is an ok song, but it's in the wrong genre.
