I find that the more time you spend going over the fine details, the more you lose the magic that makes your music special. Periphery's album is a perfect example of this.

In my world, done is always better than perfect.
It's rare that I'll do this but I agree with Gareth. You seem to put everything out to committee even when your minds already made up. Just make a decision. It doesn't matter what we think. You have entirely different taste than many of us. All of that said, autotune and vocal distortion seem a little strange in a vocal demo.
