Adoptables. I've tried commissions, and drawing other people's stuff doesn't appeal at all. And i'd probably have them as free because I wouldn't want to sell them.
Drawing people is kinda hard for me to do; I far prefer to be able to do multiple layers of refining sketches beforehand for people, but I also far prefer traditional stuff. So I don't really have a comfortable middle ground yet. If I could find a printer that could print on watercolour paper, then that'd be good.
