Not particularly a huge fan of Dubstep, but I think there is a lot to like about this mix. You did a great job getting the vocals to sit in it and work with a lot of the bass. I think the chords and melody on here are really good sounding as well and have a lot of character in them. The only suggestion I have is for how the sub-bass is sitting in the mix. I think getting the low end to fill out the mix more might help. Still, it's a fun tune.
