My only suggestion, and if you don't mind I'm going to try it later to see how it feels, would be to maybe crop the tree tighter. I feel like it might add more drama to the image. I'll post my take in a little when I can get to the computer.
Would love to see your crop I wanted the road, the fence ,the tall grass line and all the other details in the photo . For me it shows just how tall the tree .
