I do a review! :D
As far as songs for Symphonic go, there were only a few flaws with this song.
-Intro was a bit too long (First enemy would spawn 34 seconds into the song)
-Beat was not very fast ( Dubstep genre usually ran into this issue ) but that just means this song would be pretty easy to beat since it's pretty predictable.
-Fade outs at the end aren't the coolest way to end a song in Symphonic.
In terms of the song itself... nothing short of spectacular. With some slight modifications I'm sure it would fit in just fine with the other top quality music of yours we've used in the past.
