Hi !
You did well, I enjoyed the structure you created.
I found some dissonant parts in the chorus part though (made a comment on Soundcloud at this moment), but I feel you made this on purpose to keep the track dubstep-ish, so it's not a problem.
Thanks for the discovery.
I don't know much about dubstep, I thought I would not like it because of high tempo, but in this tracks the tempo seems to be low and enjoyable.
I will also put a comment at my favourite part on soundcloud.
Cheers, keep up the good work !
