Ok, this is a cool song. I'm about to make a comparison here. This is like Pendulum... aka, good drums, good effects, crap "bass," aka reese.
It seems a bit slow for dnb, and the drums need some work. The kick needs to be louder, and so does the snare. The snare needs more high texture, try layering with a hiphop snare. The pads were nice too, and added to the atmosphere..
My problem is with the reese. It was more acid, aka filter resonance, than a reese. Try using 2 detuned saws, rather than filter resonance. Its not really dnb then, more like acid breaks, or something on those lines.
It was a nice song, I liked it, but it wasn't really drum and bass. Keep trying!
