I like the effects and concept you put into this, I think that they could have been used more effectively though.
I was never into dubstep myself, neither do I have a large variety of melodic samples available to use.
Overall, the music sounds a bit messy with the absolute mass of effects added at once. There is also no progression throughout the entire track whatsoever, and the seemingly randomly placed notes are at times jarring when played with each other.
I do see potential in your music, but there can be a vast amount of improvements you could have added.
