LJ, I wouldn't worry too much about posting whatever you'd like feedback on. Someone somewhere will generally give it a listen and provide some feedback. Sure, the more esoteric the material, the fewer comments one gets, but that's the nature of esoterica, I guess.
As far as the song goes, I would doubt its commercial viability, but as a piece of art, it certainly had an impact on me, and I suspect that's what you're after. This would make a great piece of performance art, I think. You have a certain something that's great to listen to, which does make a case for creating more "approachable" songs to broaden your appeal, but I'd also be quite proud to have something like this in my catalog. I look forward to hearing more!
