Almost perfect.
To be honest with you I'm not entirely sure how you would improve on this track, I loved it. It had the ambient feel to it in the beginning, slowly adding in the other instruments and sounds. The out-of-nowhere bass distortion was nice, it broke the monotony and surprised me. The only thing I could really request is to use that climactic ending and use it like a break, only to bring the track even higher and intense. :)
