To me, the fence is too flat meaning it runs right along the horizon line and thus makes up its own plane in the photo, however there are no elements to lead you more in to the photo. The fence leads you from one side to another. I do see you have captured the bent, but it's hidden behind the flat part in front, so you're not guided inwards. I miss the depth, that i think you could have gotten by taking a more sideways approach to the fence.
I do like your choice of coloring, it fits with this image.
