Nice ambiance, feels like a trailer sometimes with the brhams of doom. I think your "theme" of the bend upward string is nice but used a bit too much, though thats the plugin you are using too I think, if I remember its from Spitfire Labs but i'm not so sure, I would love some variation like a bend downwards for a "question and answer" type of thing. Love the percussions on the first track, very epic in your face, a bit loud at some point we lost some instrumentation along the way. Very good job !
