Excellent source
This was available before Chris Hart's Chibi/Furry book and although I looked over it once, I ended up getting Hart's first. Hart has a lot of good art in his, but since purchasing this book I found it to have better instruction and poses. Actually, I recommend just getting both books. There are so many instructional books out there for manga and anime, I don't know why there aren't more for Chibis. It's such a popular style of drawing that I wish there was more art books.
