It sounds empty. You've got some good pieces in there (I particularly like the buzzing that comes in and out, that's a nice extra touch) and the sounds you've chosen fit well together, but it needs something else for how long it is. A couple more melodic riffs of the lead synth or another complimentary synth, more variation in the drums, or some kind of pad to fill in the empty space behind the music are the first suggestions that come to mind. I don't listen to much DnB and I've never heard of Neurofunk so maybe I'm just not the target audience, but my impression of this is an unfinished song.
