Simple, yet well-made.
The first thing I must note is the drop. These days, the drops are practically a joke. They're usually incredibly predictable. This one, however, really took me by surprise.
Overall, my only heavy complaint is the percussion setup. First off, I recommend putting in some hi-hats -- or, at the very least, something light and rhythmic. I'd change the kick as well, but the big enchilada is the snare/clap. Make it more hammering, more on the "anthemic" side of things.
Keep making dubstep.
