The poses in this book are indeed very dynamic and interesting but the one MAJOR draw-back is that they are all with the models laying down on the ground. Definitely not a very practical figure reference book for an illustrator like myself. I mean lets be honest, how many times are you going to be drawing a figure contorted on the ground verses standing and engaged in some sort of action. It may, however, be possible too adapt some of the poses for a standing position and yet gravity affects the body completely differently when it is horizontal instead of vertical. The photographs themselves are very poor in terms of quality in that they are: muddy, bad resolution, slighty out of focus, badly lit etc. etc. etc. Basically this was a very disappointing purchase. The "Fairburn System" series is far better than this book for photographic figure reference material; however, very hard to find.
