i listen to a lot of dubstep so i'll offer some criticism
a nice idea, but i think you need an instrument that sounds more epic and less cheap for the trek sample
the drums are way to quiet and unremarkable anyway
the bass is too standardized (it's either got to wobble or sound stoned, dubby - and definitely you need to use a mastering plugin to pimp them a bit more)
the drop is pretty weak and doesn't have a great buildup or a surprise moment in it
maybe you should have played around with it for another 2 hours ...
all IMHO, of course, subscribed in any case to see how your sound develops
edit: if that seems a bit harsh, then check out this great epic sci-fi dubstep tune, which is the standard i hold good songs to:
