illustrationclass.com is an awesome resource created by Von Glitschka, an Illustrative Designer and 20 year communication arts veteran, for students and professionals alike who want to incorporate more of their own illustrations into their work. illustrationclass.com is loaded with creative exercises, tutorials, handouts, and all sorts of great illustration related materials to help all levels of designers who want to do more of their own illustrations. Very cool. Check it out =)

I saw Von speak at HOW this year in Boston and he was awesome! His presentation along with all of his materials from HOW are available on illustrationclass.com. It's very cool (not to mention generous) of him to have made this all available for free on his site. I strongly suggest you download it and check it out, great stuff!
