It's probably the placement of the subject. She's directing the focus totally off the scene. Move her over 1/3 to the right. Also you might have to do something about the background placement so you don't get mergers or too distracted. (Same rules as with getting a good picture in photography.) Other than that, dunno what else could be done.
