Her legs are very awkward, especially with the direction the feet point. If she were swinging around for a shot, her left leg would swing out as well. My advise is to physically stand up and try the pose to see how easy/difficult it is to do. My suggestion is to swing the left leg out, foot pointing in the direction of her hands, and for her to be descending into a partial crouch. If someone's shooting at you, you want to make yourself a smaller target, anyway. One of the best pieces of advise I ever read for posing in artwork is to imagine each action from begining to end and only show the begining or ending stance. (Think of a baseball pitcher - the exciting poses are the start of the wind-up and the release of the ball. Everything in-between looks awkward or dull.) Hope this helps!
