Female back...

When comparing female anatomy to male anatomy, the first thing you'll notice is that her lats don't give her that wide-back look. Also, her traps aren't an accentuated muscle group because she needs a long, supple neck to retain her femininity. Never draw her external obliques as separate muscles, as they appear on a man; there's no "bump out" of the obliques. And, she has wide hips and full, muscular thighs. Also, square-not drooping-shoulders are a feminine look.
