Wow. I actually like this.
Two things do stick out a bit. A little too much compression artifacts like someone else pointed out. Heavy compression isn't a bad thing, I really love what Kate Bush does. But not when it gets too distracting. The level of control you applied to sibilance is pretty nice, though.
Then there's a bit too much room resonance or reflection that is also a bit distracting me. This, along with compression artifacts, is making the track seem a little uneven in some places. Especially in a few spots where chest voice (or whatever they call it) sticks out.
I noticed these things because I am very critical when I track my own vox with similar issues at times. But then again, It's not like I know the answer to them, however.
But boy, I do like what you've pulled off here. When you do retrack, I hope you re-capture the essence that makes this track interesting.
