First things first, that Far Cry 3's "definition of insanity" sound clip is copyrighted (even a short 5-10 second clip is a no-no), sadly; and therefore cannot be posted here on NG. You'd be better off posting the version with the voice clip on SoundCloud and posting a version without the voice clip.

Did you use FL Studio's stock kick and snare sample? It be better if you'd avoided using 'em dryly (without processing the shit out of it).

You could give the drums a bit of variation by throwing in some hi-hats, or maybe removing or adding more kicks in there.

That little break at 1:55 till 3:25 with the voice clip is...well, WAY too long. You could have made some sort of progression (adding more elements/instruments). And the cut back to the filthy wobbles, with all that tension from the previous few seconds kinda kills it. Try putting in noise sweeps, or giving that string tension some reverb.
