honestly, im not really seeing this as a "rule of thirds" kinda shot.
to make the tree in a "thirds" section, it would have to be a pretty wide shot, and the tree would be a lot smaller in the frame.
for this shot, I like the tree larger in the frame, if not most of the frame.
focus is a little soft though. shame about the tree on the right. is there any way to get a better angle on this shot?
