Hmmm... Decent, I guess. Really like those plucks at the beginning. I feel like you need a bassline for this, as I don't really feel one present except for the beginning, where the sub bass are present. [correct me if I'm wrong here] Drums are okay, really like the fast hats, although the snare feels a bit muddy, especially when it builds up at around :43. I feel like the way you used the vocal samples feel pretty lacking, as it's only used as atmosphere and not a part that's supposed to compliment the main melody after 1:51.
