This is a good book for beginners to portrait painters. The first chapters provide a solid basis of how to draw people, applicable to painters in all media. Emphasis is placed on the head and its features, on hands, on limbs, and on the person as a whole. Basic anatomy is used to explain why people look the way they do, and how to draw them accurately, but it is kept as a support to the direct 'how to' instructions given by the author.
I like that part of the book best, it is a solid foundation on people drawing. The last three chapters of the book go on to apply these basics to specific painting media - oils, pastels and watercolour. Although providing useful information, these contain fewer gold nuggets than the early sections.
