It's listenable, but it doesn't exactly speak dubstep to me. Tempo is right, but... There is so much reverb, and the low frequencies are almost painful. Interesting soundscape in the higher frequencies, but it really does not feel to me as if it progresses from 00:20 to the end. Same dry drum loop, same papery sounds pulsing in and out, and same violin. Not my cup of tea. Sorry. Outro is nice, though.
