Wow... as of today, I have been a member of deviantArt for 7 years.
Mind you, about 5 of them don't count. I created my username a long time ago after somebody did pencil sketch copies of my art without crediting me, and I wanted to chastise them.
Then I largely forgot about the site. I had my own art site, and that's where I put my pictures. Then I stopped painting altogether for three or four years and did nothing but comics.
Then a couple of years ago I decided what the heck... maybe I'll start painting again, and put my art up here. It might gain a few new readers for my comic.
Two years and 400,000 (!) pageviews later, and my old art site has gone and this is the only place I put my pictures!
I would like to redo my art site though. Have a nice little portfolio going, feature my best works, link to all my graphic novels.
