I like them all; but perhaps I am somehow biased toward paths and fences, as I tend to photograph them a lot myself. Risking to be called "the crop boy" in this forum, I would try some cropping on them, just to see what happens: on the first two, I find the sky too bright; on the last one, there is an uninteresting zone at the lower right corner. I would also play with the curves: even if the photographs do not seem overexposed at all, some darkening may add to the final result. Just my two cents.
