I agree that this is a keeper. What I like about this shot is the quality of the light, which was lacking in other shots of yours (for instance, the pastoral shot of the horses). While I am convinced the composition works, it could have been even better if the camera were shifted slightly to the left during capture. I like the details that the in-focus leaves provide, but directly to the right of it there is empty space that could be sacrificed to improve the overall composition. If you had shifted slightly to the left, the yellow/orange leaf would be in an ideal spot regarding rule-of-thirds. Nonetheless, as it stands, this shot is probably the most beautiful that you've posted here with respect to quality of light.
