Let me get this out of the way right off the bat - this whole thing has a "Radio Shack keyboard demo" vibe to it. What I mean is that everything sounds like midi to me.
I think the kick needs to come back, and the snare needs to come up a bit, especially during the second theme when the flute takes over and the drums switch to ride cymbal.
I think on the recurring "guitar" keyboard part (maybe percussive organ?), you need to really concentrate on making all the notes in the chord hit at the same time. The attack on that patch becomes very distracting if you don't hit it exactly. This is especially evident toward the beginning of the track, but it's still there through the whole thing.
On the subject of attack, the french horn patch sounds sort of muddy when in unison with the percussive keyboard/guitarish sound. Why? Because the percussive patch has a quicker attack, which makes the horn patch sound late. Maybe slide the horn part over by just a millisecond or two... that should clean it up... unless that 20th century electronic delay is what you're going for.
All in all, I really did like the tune. I think if you put it in front of live musicians, though, the song would really benefit. Good work.
