I've viewed your gallery and commented on your shots before. I typically love your landscapes, but this one doesn't do too much for me. Firstly I'm on complete overload from fall postings of the leaves changing colors. That's not your fault of course. Secondly the negative space in the foreground really draws my eye away from the tree. Finally, the sky is a little too green.
I agree with Brandon as noted above. The placement of the tree looks great. The focus and clarity are right on the button. I sure would like to see a little more narrative. Maybe like where and when it was taken, even some details about weather and your camera.
