Deviantart is a good page for presentating art, still there are some restriction with DA on what kind of art is allowed and what not.
So here are websites where I upload more stuff like flash games, adult art, or progress pictures, sketches and so on.

Facebook: [link]
My Blog: [link] (sketches, wip, will add flash games later too)
Pixiv: [link] (adult stuff mostly r-18, don't go there if you don't like it)

Have fun!
