Good...
But it turned me off. The intro was pretty good... but it was hellah long, man. And the very beginning, the transition was waaayy too quick. You should have left the pianos be for a good 32 seconds more or at least made it 45 secs longer before you transition into your second mood. It's like you have too different songs in one. I would have put that transition in the middle.
Next point: this is drum and bass, correct? For a good 1 minute+, there was nothing... but synths, bass, and that weird distorted click noise... which got annoying after a while. It was pretty random. And the way you brought back the pianos and still left that noise... this song does not feel like it is in order. The structure is very odd.
Third Point: near the very end, I hear the drums... after a good 1:30 mins of synth. I'm sorry, but that just doesn't do it for me. You are going to have to redo this one. You really need to stick to one emotion: etiher those pianos and a better bass, or that bass+noise, or a better combination of the two. You need to work this one out, and give it some more time. It sounds too haphazard and too abrupt.
As for the drums, you need to lower those volumes, or compress them so they don't sound too loud. Keep working at it.
