It’s a very early version with hardly any variation in the beat etc but I think it’s pretty good so far, I also found a use for the Slayer VST at last!
The snare sounds good to me. I agree about adding a bass line.
But what I feel is missing the most here is more energy to the beat. If you want a typical DnB sound try adding a couple of long deep bass drums, sliding down in pitch. What I’ve also found is that ride cymbals really gives depth to a DnB beat. Just make sure to play them somewhat chaotic, i.e. not on each 8:th line or so…
