I could have sworn I'd posted in this thread, but it doesn't seem like I have.
I'm a professional illustrator - which means I switch between having nothing to do but draw my webcomic, and being ridiculously super-busy at irregular intervals. I've worked with illustrating textbooks (something I still do), drawing book cover illustrations, doing 2D illustration for indie games (something I really want to do more of - it's fun!), etc. I've also done acrylic paintings on commission.
So yes. Always on the lookout for more work.
