Even though you have that drop a 1:12 it is not enough. And with the wobbles all through the song you don't really have that impact that dubstep should. While I was listening to this song I kinda just listened and it didn't seem to vary. Try making you drop harder and staggering your wobble into sections of the song, having those deep warping and wobble sections is what I find to be really crucial to a dubstep song that gets me into it.
Please contact me if you would like to use this in a project. We can discuss the details.
