This song is very calm indeed; very light. I'm thinking, even though the song does blend together and flow very well, at the drop, you should make the bass a little bit more "known." Around the beginning (at 00:55), try to work on the change of the song a little bit more. Make it flow naturally.
I am trying as hard as I can to explain what I mean.. I promise you I am not trashing your song. I actually enjoyed it. I can just be a bit of a critic (especially when the permission is given to me to do so).
This song has a lot of potential, and, as said, is very soothing and calm. Just work on that song morph and that drop a little bit more. :) I know the difficulties of making dubstep (none of my recently created tracks are uploaded since they're still works in progress).
