Here's a whole mess of drawings I've done of other people's characters - most were private commissions, some were for fun, a few were try-outs for freelance jobs. Try and guess which is which!
I don't really do private commissions like these anymore BUT- I am running a Kickstarter campaign for my new book THE COMIC BOOK HISTORY OF ANIMATION where a private commission is one of the pledge rewards. So go get one!
