It's pretty cool
It's a shame, that the score was pretty low, but overall it was good.
Still there's some work to do, of course :D
I'm not that much into DnB myself, but it would be nice if you put in some sort of lead melody, that gives it its own more unique sound.
Furthermore, at 0:22, The first part, where the 'full' drum pattern kicks in, You have, right before the snare, a slightly softer snare. To be honest that one bothers me a bit.
Also, the bassline slightly fades away quickly every now and then. I'm not sure if it's the kick and the rest of the beat that makes it sound like that, or that it was done on purpose, but either way, it's not a great sound to listen to, a half-fading bassline like that. Maybe you could compress the kick, or slightly turn up the volume of the bassline.
I really like the bassline in combination with the percussion you used (of which I must say that you've done a really good job there)
Well, I hope that helped you out a bit, but the atmosphere was really good, and with some improvement here and there, it could turn out great! :D
Good job, keep it up!
