Good use of lines. I'd even go tighter on the the crop to bring attention to the fence. IMO...the space in the upper right corner of the photo takes away from the fence as the focal point.
very very nice. Great use of B&W, and plenty of contrast to provide me with texture and to define each subject. The odd angle is great. a little background to provide context, but I remain focused on the fence. very nice indeed.
I would crop out the sky entirely, this would direct our focal point directly to the fence post. As it is, our eye is drawn to the sky. The eye is always drawn to the lightst part of a photo.
