The end of the chapter then lists the other principles and thumbnails of the demo painting to show how those 4 remaining principles apply to it.

Not really for beginners, but more for the serious artist, the writer provides extremely detailed steps for each technique. "This is a book that rewards the eye as much as the mind, and it is a feast for both. If you aspire to greatness in your figure drawing, then buy this book, study it, and apply the lessons."
