Hi tkbslc,
You are standing on the ground, not same level with the middle of the tree. Also, you didn't focus on the tree, but
the leave at front.

You were shooting at 225mm which is quite a large focal length.
This will give you shallow DOF even at f9.
According to the DOF calculator, on a crop body, say, at 20m away,
the DOF is less than 3 metres and only about 1.6m behind the focus
plane.
So you are implying that the tree is leaning? The top is more than
1.6m farther back than the front? I find that very unlikely.
