Sounds good. I've never heard the original, so I can't compare.
One comment I have on "Alteration" is that the drum stick on the side of the drum, or whatever it is, that begins tapping about a minute into the song is too loud and kind of overpowers the melody (because it's a fast, sudden drumming sound, I think my ear is drawn to it and focuses on it too much). I think it would sound better toned back a bit.
