Apparantly this website has been around for a while, but I just discovered it. Illustration Mundo is a great little site for freelance illustrators. There are articles, book recommendations, a great little forum, and if you are a professional illustrator you can advertise your work for free, complete with a large thumbnail that links to your website. You can also rate other artists, add them to your favorites, and track news of their latest goings-on. I’ve seen some illustration sites that are, well, less than professionally done. But I’m pretty impressed with this one. Check it out.
