Rhodes - I love how the sound of the singing voice sort of transforms into a Kokyu before it fades out. Although I thought the synth at 2:40 was kind of rough, and out of place...Almost like it was too acidic.
Over all, a very nice peice. I like how it subtly modulates between beautiful and dark, tonally. Sounds like something I'd hear on the Sim City 4 soundtrack, and by the way I though Sim City 4's soundtrack was very attractive!
I'll see if I can crit your other songs a bit later, I'm a bit exhausted atm.
