Nice job ... the opening's terrific! I liked the tempo change -- a song like this that goes for 4.5 minutes tends to need something about 2/3rds of the way through to snap you out of the trancelike mood it creates and make you pay close attention again. The tempo change did just that for me. I thought maybe something heavier sounding would fit nicely when the slowdown happens though ... something that would make it feel like it's dragging on the tempo? That might make the slowdown it feel a bit more natural. Hope that made sense. Also, what about a short reprise of the freaky piano from the beginning for a little tag on the end? Would tie it all together, you know. Anyhow, overall I think it sounds great. :)
