Stephen Silver is a character designer who has worked for Warner Bros Television, Disney Television Animation, Sony Feature Animation and Nickelodeon Animation. He's also one of the instructors at Imaginism Studios.
This month, his new book Passion for Life is coming out. It's on life drawing. Advance copies will be available at San Diego Comic Con 2009 at his booth H-6. You can also find his book at his online store. I'll be posting some reviews for his books next month, after the comic con.
Meanwhile, you can check out more of his work at stephensilver.blogspot.com.
