My first impression is that someone was about to jump out of the bushes at her as she looks scared or anxious. With a bit more focus and perhaps a bit more overall contrast I would have scored it higher.
I took the liberty of saving this photo and doing a simple levels adjustment (Black = 25, White = 186, Gamma = 0.90) and it made a world of difference. Right now, this photo is quite lacking in contrast and has a very narrow tonal range (it consists of a very narrow range of shades of grey). That there are no pure black and no brighter areas leaves the eye wondering where to look. Increasing the contrast with levels gives shape to your subject (right now she looks very flat and two-dimensional) and brightens it to make it the focus of the photo.
