It is dubstep alright.
Now, I would prefer some more low pitched and high basses, but heck, matter of taste.
Clever middle drop too, haha! :)
Though, I personally think you are much better at dance than anything else. However, it is always good to go and try other genres.
I really like the way you blended dance with dubstep here.
I heard some crackling near the beginning, don't know if it was just me or my speakers, haha :)
Good luck on the full track! :D
