This is a truly good book if you like to draw male office workers, like I do, so yeah is helpful it show you different poses, styles, personalities, ages and situations of office workers. And is also so good that includes some tutorials, process and interviews. I really like this style to draw so this book is going to be a good one to check for inspiration. I truly wish for this kind of book to be translated and sell in america because this kind of reference books are just great and inspiring.
