Interesting subject at an interesting location.
- There is a lot of empty space back here that doesn't add anything to the overall image. Maybe if there was a dog or cat back here...
- There is a saying in photography, Dead-center is deadly. This is a rule that is made to be broken, as long as it's intentional.
I'd like to see a little sky. It doesn't have to be much especially if the sky isn't interesting. Where is she looking? In general you want to have an object either coming into the photo (a dog, bird, etc have room to move) or if it's a person, give us an idea of where they are looking. It doesn't have to be a lot, just someplace to look.
I cropped this down to put her on the right side looking out. I also added a little contrast.
