Not bad, but I wouldn't say this is DnB. It's closer to Dubstep with the pacing and tempo, but even then it's a blend of so many genres that it's hard to say. Your drums sound a bit flat and are lacking high end and punch. The mid feels too high, and the overall presence of the drums could really just use a lift. Your lead could come down just a little, as well as your ... is that a vibraphone arp? Certain sounds are just too loud and have what sounds like a little bit too long on the reverb. Writing is nice though, and so is the spoopy feel. Nice work.
Quick question: Are you listening with headphones or through speakers?
