Consider uploading this track to a streaming audio site like Soundcloud or even Youtube. You'll get more listens instead of having someone download a file plus you can set permissions on it, etc. This would hopefully get you some more feedback. At the very least - consider a smaller file size than a WAV. I would listen but I'm on my laptop, have no headphones and around my newborn niece so sleep is a gift from the gods right now.
I will listen when I get back!
