When this book says "Mini Manga" and "Pocket Reference" . . . it means it. The book is about 3 by 2 inches. I've never seen such a tiny book! For all that it's miniature, it packs a fair amount of information. It covers the basics of what you need to start drawing, such as pencils, erasers, types of paper and ink, etc. Then it goes into the formation of the hand, the bones, then the flesh over them. It gives demonstrations for drawing the hands in various poses, such as gripping a sword, folded in prayer, and so on. Very elementary. The section on feet is much shorter, but still effective. It shows the feet in a couple different poses, and then wearing several types of shoes.
I'm giving this book only four stars, because when it said the book had 200+ pages, I was expecting quite a lot more than I got. The small size severely limits the amount of information that can be included. It's got a lot, don't get me wrong, but not nearly as much as I was expecting when I saw the page allotment. As I said, it does cover different poses of hands and feet, but it's very simplified. You don't learn much about adding shadows or form, for example, or how to color in the figure. You just get the basics: how to draw easy comic-style hands and feet.
I'd recommend the book for kids or teens who are interested in manga or comic drawing, or as a primer to teach the basics before you go on to learn more about how to draw the human figure.
