For me, the highlight of the song is the fluctuation in tempo throughout the theme. The first time I listened to this song, I remember being kind of thrown off guard by the 1:11-1:16 point. However, I understand its artistic purpose. Great job with bringing the song through its various highs and lows.
I love the dark, frantic feelings behind the beat. The song is more of an ambient track, I find. That's not a bad thing in and of itself, mind you. It's just something that works better in the background, rather than a piece an individual can actively engage. Still, great work!
