I own the previous editions of this series and find them very helpful when I don't have time get to a Life Drawing class. The selection of body types, ethnicity, skin tone and coloration in addition to a wide choice of gesture poses, particularly online, has helped me improve my drawing skills more rapidly than I would otherwise have done.
The photography and lighting are professional and varied.
I would recommend the Art Models series as a good adjunct to life drawing.
