this is also my third time looking at this picture, and i decided to leave a comment :sweatsm:
you've got a sweet looking subject, but i'm not quite agreeable with the background which i feel you might have originally included to follow some rule of thirds. i think a square crop letting your subject fill up the entire frame might work better, at least for me
Can be better if there is directional ligthing from the side. Can be done if you have professional gear, but if not than just change her position vis-a-vis the light source which I suppose is the sun on a cloudy day and close to noon. And also take at another time, like earlier or later.
