I like it but maybe a fraction too much tree?
What is the subject here? The hat, the tree or the model?
The hat and the tree overpower the model and that is not ideal.
Agree with Geoff - perhaps crop off at least a quarter at the left?
I agree about cropping. Maybe from the top as well.
I don't mind the cropping. However the brightest area of the photo are the hand, shoulder and arm. Perhaps you should tone down all the area below the finger, including the finger and lighten the face and eye slightly. Simplify by emphasising the face and hat, leaving the rest as supporting background.
