love the picture. i do have one thing i'd like to mention though. the exercise she seems to be doing (barbell shoulder press,) would not use that pose at all. when you extend out for the press you actually want the bar to be right on top of your head and keep your back straight, you don't want to be arching back like that. i know she's not fully extended yet, but she should still be close to nearly straight. if that was done in real life it would probably hurt!
sorry for the rambling, i DO love the pic just thought you might be interested in that tidbit. if not just go ahead and ignore it.
