I did these covers for Capstone Press last year. I only just noticed them on Capstone's site, I have no idea how long they've been public.
Below are some larger versions without the type.
Being children's books I definitely was pushing the cartoon aesthetic a little more than usual.
In the end I felt like I got some fun images, though like with any work under NDA, by the time I finally get to post it all I can do is think of what I would have done differently if I were doing the job right now. Thanks for looking, all!
