I like the way the fence draws the veiwer's up and in through the image. I see a full tonal range, but I feel that some of the fence and barn are too bright and some too dark. The sky is nicely exposed, and I like the depthe of field.
Nice composition and the fence acts as a good leading line. I think that B&W was probably a good choice for this, as it tends to hide high contrast light a little, but for me, the high contrast light is too much for the scene to be captured properly. I know it isn't always possible, but later in the day or earlier in morning when the sun is low would offer better lighting. JMO.
