I do. Maybe too much. Fanart is cool and all... but as an artist, I will not be able to do a living of this lol. And besides, original work is cool too. It's your own stuff and I like to create original characters. It's harder because you decide the canon yourself, and so, it can change all the time (contrary to fanworks, where you already have a canon to rely on)... but when your own creation finally comes alive, it's wonderful.
