Tio-- I bet you really love the Matrix movies, don't you? =) (just teasing, don't take it to heart). The Gothic gallery is pretty similar to what you are talking about in my opinion. And, honestly, I think that people are reasonable enough on average that if you want to post something a little darker, they won't downplay the rest of your art just because of that. I've seen folks with entire galleries devoted to pentagrams, vampires, and dark evil, and they get tons of viewings and comments.
