Hello Greg,

That's a very cool song! Great composition!
As for the vocals, if I were you I would use some equalizing and cut down the high frequencies just a little bit. Furthermore you might want to add a little bit (more)reverb on it.
A nice tip on improving 'those hard to reach tones' in the vocal part. You might want to give the GSnap vst plug-in a try. It is a free auto-tune clone and can be downloaded here:

We use it occasionally. It works very well in most DAW's.

Keep up the good work,
Rob
