Query: Not a bad book

its the first "how to draw manga" book i had ever bought, so its quite hard for me to judge how good this book is. but anyway, i find this book interesting and its very organized. it teaches you basic beganner stuffs and then slowly show you the professional way of doing it i am only half way done with the book and i had learn much, its a book better then an average "how to draw" book
