I support this idea. Since this place is a community for furries or people into the furry fandom, I doubt that the non-furry theme would dominate the site. Plus it might open the door for some who aren't good at furry art to be able to feel confident enough to give it a try. Since most of my drawing style stems from drawing humans and fantasy races (my new furry works far outnumber new works of those), so it would be nice to post some of those things when they come along too.
As a community, i've always thought it important to have a place where furries could share their art with eachother. reguardless of the medium or genre. I know ArtistsWorld will likely cover the non-furry/alternate genre art, but I for one enjoy my friends here and enjoy sharing with them.
