Actually, I like this image, the only concern would be what would the image be used for? In my opinion it could make a great stock, lifestyle image because the subject is "interested" in something by the look in her eyes and the environment.
Second, the "warm light" is great, adds mood and intimacy to the image along with the contrast the light and the model's yellow shirt give to the blue sky. Opposite colors, warm vs cool, normally make great combinations too.
Finally, you have leading lines caused by the backstop/fence itself, that is a great way to compose an image, leading the viewer into the subject. Overall, this is a great image in my opinion. Thanks for sharing, rg sends!
