Her legs don't look right because the way they're posed makes no sense. Her right thigh is in front of her left thigh, yet her right calf is behind her left calf. Both parts of a leg should be in front of both parts of another leg.
She's off-balance. If her legs are tilted to the left like that, her top half would be titled to the right, and her arms would come into it to compensate. Her left arm (our right) would be higher. Her arms would also move with her stride...meaning the arm opposite of which leg is forward would be forward as well.
Your right. Now that I look at the reference it doesn't look right at all I just thought the flow was cool at first but now it looks flat. I think the new one I did feels alot better and flows right. It looked like she was about to fall in the other one. xP
