Dude this is a badass song :D keep up the good work.
It doesn't actually sound like real DNB. It misses a loud real kicking beat and decent drums. The composition is nice though. But the sound quality isn't that good. I think you mastered (good) a badly mixed (samples) track.
P.S Check out my latest track: In My Mind
True, I did soften the bass drum sample a lot. I only called it DnB as it had that Pendulum beat originally.
I shall spend more than half an hour on the drums next time, cheers man. Shall check out your stuff.
