Not feeling it
It just doesn't have the elements of dubstep... or anything for that matter. Belongs in the miscellaneous section in my personal opinion. But enough about genre choice, let's get on to the review...
The little vocal clips are, well, annoying and repetitive. Your drums are a little boring and the kick doesn't exactly have enough vocal presence. Finally, your pads and synths don't exactly match each other.
Overall, you fell pretty short on this. That doesn't mean in any way that you can't improve so keep going on. Good luck in the future.
