I haven't really looked into other art communities, I'm not sure how much help I'll be. :\ Either way, it's a shame that your art isn't finding much of a reception, i think it's really inventive and gruesome/squicky in a great way.

Maybe you'd have better luck on someplace like tumblr? There are a few crappy things about it, but really that's just because there are a whole lot of people there. There's a bunch of sub-communities over there that are into specific themes etc, and you might find a number of cool artists to influence/find influence in. It's more general-audience than the furry sites, for sure, yet it goes way into extreme territory at the same time.

Whichever way you wind up going, I hope your traffic and comments pick up soon. Nothin' feels worse than performing for the crickets. :c

You can join the many theme groups on DeviantArt. They can garner followings by showing how your style draws the eye and mind.
