Hrm, the book itself is actually good. It's just that the specific shot you used as a reference isn't the best one on portraying a female body... As a supplement I'd recommend you check out Ron Lemen
http://ronlemen.blogspot.com/. He's done some excellent tutorials in ImagineFX, and his gesture drawings are simple enough to deconstruct. He put me back on track in terms of anatomy.
A lot of art isn't exactly about what's real. What matters is the perception of reality; what we
think is real. A bright red blob in a fruit stand will be seen as an apple. If it were a green apple, chances are you'd see it as some vegetable instead. It's the same with stylized anatomy. Females are more curvaceous, males have more straight lines. Females generally have lighter frames, males are stockier. Hybrid body types are much more difficult to portray, so be extra cautious when doing them until you're comfortable with the known archetypes (hybrids would include muscular females, effeminate males, fantastical humanoids such as half-elves, cyborgs, etc.)
Hoping to see your progression here, hehe.
