As an artist and sculptor I have found this book a valuable addition to my anatomy reference library. It has what almost every other artist anatomy book is missing. Well lit Photos that correspond to illustrations of skeletal and muscular structures. The facial muscular system is better described and laid out than I have ever seen in artistic reference material. My main beefs with this book is the lack of variety with the models. I would like to see examples of fat distribution as well as the focus of muscle and well defined males. I would also like to see the same attention given to female anatomy as was done for male anatomy. I do realize this would double the size (and price) of the volume but for reference of this caliber I would readily pay for it. I have also found the accompanying texts are heavy in medical lingo that doesn't serve the average artist, but the images well than make up for the text. Over all an excellent reference book.
