I've been doing shota and lolicon doodles, but I can't post most of 'em here in full versions. X3 So I just wanna share where I've been posting!
The spot that's most like IB and FA is y!Gallery, and so I have a site there: http://yaoi.y-gallery.net/gallery/bosky/ . It's got a cool community, definitely! There are lots of rules though, and so not everything I'd wanna draw is allowed. So I started a thread on notfourchan: http://notfourchan.net/ic/res/407.html and I've got a thread on LittleAngelsHentai's artists forum too (with the same stuff).
So those're the places I know about! Oh, and Pixiv, but I don't understand the community too well since it's in Japanese. X3 I'm still open to suggestions about other spots to post, especially since right now it's gotta be kinda scattered. :)
