I just posted this screencast video on YouTube where I critique vector art created by a beginner Adobe Illustrator user. These critiques apply to any vector art software.
Just a quick news item: the Adobe Illustrator CS6 version of the superb Illustrator WOW! tutorial book series for Adobe Illustrator will feature a lesson by yours truly.
I was approached by the author, Sharon Steuer, to contribute an advanced technique to the book. We decided to present a unique method of quickly applying color to your line art using Adobe Illustrator’s Shape Builder tool. The cartoon logos and cartoon characters you see on my website and blog are created using this technique.
