i have an account on shadowness, but they don't have a freakin' text submission interface (the last time i checked) so they aren't particularly supportive of writers. mostly, it's just dA. there's enough going on here to keep most anyone occupied.
I've been on DeviantART for a long time now and I love it I haven't tried any other art sites so unfortunately I can't help you there. Have you tried uploading your art to Facebook? Millions of people use Facebook so your art would get a lot of exposure
