Resource: DeviantART

I'm sure this won't be news to a lot of you, but DeviantART is a great online art community, there are some really fantastic artists and photographers on there. There tends to be a focus on manga/anime and digital art, but there really is a wide variety once you start poking around. You can set up your own gallery, comment on everything, save your favorites to different collections and all that fun stuff. It's a little bit like a myspace for art. Great for finding those new artists too! :)
