I like this picture but I fin the drop shadow border is distracting (I keep looking at the border rather than whats inside of it). If you do opt for a border in the future I would suggest keeping it really simple and plain.
In terms of the picture itself I like how you used the corner post to tie the image together visually. The fence draws your eye into the picture creating a nice feeling of depth.
There is some interesting elements in the picture without it being too busy. (the fence, the tree/post, the pair of trees in the background; the nicely contrasted clouds in the sky).

I like this alot. It has a greeting card kind of feel for me for some reason. I've always loved compositions with old fences in pastoral country scenes. Nice light and shadows!
I would have liked a little more of the road included to give the feeling of "going somewhere". Clouds are nice, but the foliage is a little dark. Your border technique is very interesting, but not sure it adds to the photo.
Nice composition with the road and fence positioning. It appears that a deeper aperture could have been used to bring the distant tree into sharper focus. Overall this has a very nice feel to it. Best of luck to you in the challenge.
