Awesome what's the song ID?
You should spend a little more time on your songs. A good song is more than just putting notes down in a program. Not sure I would classify this as dubstep - it lacks the "wub-wub" effect that basically defines the genre. Also, the song was too repetitive for my taste. On a positive note, you used the scratch well, and that can truly add to a song if used in the right way. So keep trying, and put more time into the creative thought process.
Please contact me if you would like to use this in a project. We can discuss the details.
