Excellent use of hi-hats and cymbals. Great snare work, unique distortion on the bass. It got pretty Aphex Twin-esque on some of the better parts.
The only problems I have with it are conceptual. I don't really understand the idea that ties the samples together. That same sort of thing goes with the song as a whole. While it was, on a technical level, impressive, it lacked character. It didn't flow the way it could have.
