My sister had bought this book because she was interested in drawing manga a small bit. I flipped through the pages and found it very misleading for a "manga" instruction book.
First off, this isn't manga; though it may seem very stylistic and similar to the real thing it's not showing you how to draw manga, it's showing you how to draw American cartoons. The reason that it's not manga is that they pinpoints in the style of Japanese comics were missed a bit. The eyes were probably the worst aspect of this book being "fake", they were opaque circles with random shines within them--all style, no substance. The hairstyles did not show diversity, all spikey, while real anime/manga hairstyles had meaning to them or certain patterns. The sections on drawing character stereotypes were very pointless and long, considering that the author could have just written "here are the features of a [insert anime stereotype(s)]" insteading of having a detailed instruction that wasn't even necessary.
The best aspect of this book was the detailed instruction to drawing anatomy and proportions, not manga. That seemed to be the only somewhat useful part in the book.
Overall, this book receives about a 15% in grades, not good. If you're looking for an introduction to drawing MANGA, buy Katy Coope's book, but if you're looking for a simplified version of drawing anatomy and proportions, buy this--don't let "manga" in the title delude you into thinking that it is the real thing.
