I've been on DA forever, and I like it there a lot. Not ashamed to say it. The real problem with DA is, there is no adequate substitute anywhere on the web. So even when they do questionable things like replace their perfectly functional site with screwy Eclipse, there is still nowhere better to go. You should be able to find kindred spirits through groups and by tagging your work. Yes, a share of renders are a little porny, but nothing like what you find on newgrounds, hentai foundry, renderotica, etc. And there is plenty of very good 3D work and other art. It's worth a try.
