Wow, this really reminds me of Moby, what with the 808-ish drums and the flowing pads. Very intricate, lots of things going on.
What I think brings this piece down is the repetition...that main pluck just gets on my nerves after a while. Change things up a bit, go for a different chord progression, SOMETHING.
Besides the repetitiveness of the chords and the main pluck, it sounds great. I love the drums and the layers, although near the end I think you could have even more stuff going on in the stereo spectrum, it seems too mono to me.
