I like being able to see her full length and not hidden by stalks. The empty field is very evocative.
Her pose and expression come across well.
However, there is a tension in the picture which I think is to do with her eye line and body angle being where it is in the picture. I think this tension is related to the composition and it does not leave me wanting to keep looking at the picture. It is an emotion but I am not sure it does the picture any favours.
There are many other aspects that work really well for me, the colours, the light, the pose, the clothes.
