I just saw how far her hip stood out and also how there's whitespace between the top of the armor plate on the hip and the bottom of her ellbow. For me that looks like her hip is slightly off, idk what's the problem with pointing that out. Obivously the anatomy in this concept is pushed, it was just my opinion and that of others that it may be pushed a little too hard in that area, that's all there's to it. Designs usually shouldn't require the viewer to "look closer", but since this is a quick piece, no harm done.
I agree with Bane, ther is a sort of tangent between the weapon handle and the right hip and the strange pointy armor piece, so it's leaves place for doubt. Though she has super sexy curves, you know your way through exageration ! Very nice.
