I noticed right away that this piece is mastered very loud, which I admired. The easy-flowing piano lines have a very bright and uplifting feeling about them. I enjoyed the synths and mostly mellow vibe up until the drop. The drop kind of felt out-of-place. I wish you led up to it a bit more, although I do commemorate your making this song a reasonable length (7 minutes for "Horizons" was kind of pushing it IMO). I definitely liked the "spaciness" of it, though, as you alluded to in the description. Another feel-good piece, so much so that I may go as far as to call into question its categorization as "dubstep." But honestly I don't really care what genre you put it into. Just do me a favor and keep it up! ^_^
