IMO The epic feel of this song at first is almost like a trailer for a movie where a giant spaceship is about to be sucked into a black hole.
That goes away after the initial triplet-style dubstep-elements come in. After those initial dubstep parts, it goes back to being the trailer. Then the second, non-triplet style dubstep elements kick in and it feels like an escape level in a video game.
I think the triplet-dubstep elements are the one part that gets in the way of the vibe it seems to me you are going for the most.
Otherwise, I think your intent is quite well expressed. This includes the thumbnail artwork and the title you chose.
I hope this helps. :)
