Weeell, this really isn't dnb. The tempo is slower and your drums are not punchy enough; nor does it contain a breakbeat. bmph tss bmph tss = house/trance! fast overly processed breakbeats = dnb
I think it's a pretty ok track. Your kick sometimes interferes with your bass; you should try to boost the volume of the kick around 90-100Hz and cut off those frequencies from your bass so they don't clash but work together. Try to eq your snares so they have that ~ 220Hz 'pop', roll out some of the high end and then compress it to make it sound more aggressive.
I liked where you were going with the piece around 0:50, being a bit more calm. But then the arp synth comes back in really violently. Maybe you could have it 'ease in' a little by having it start at a real low volume and gradually upping the volume or cutoff. (A lowpass would work I think)
All in all it was enjoyable. Keep it up man. :)
