great pulse, almost reggae-like, fun. Particularly liked the middle section, when it got a little more sparse.
I would vote for nuking the square-wave type lead synth in the first part, maybe this is where your someday singer would dominate? The square wave didn't stack well with the more organic violins and such, in my opinion, but your may vary!
It would be pretty difficult to emulate Enya and her mixing techniques, and I think you have done a first-rate job.
The ending could fade out, or come to a conclusion, but as of now it just kind of stops as instrument by instrument sort of drops out. What about a nice, long fade? What are your plans?
good job, man!
cheers,
