What really makes this photo wonderful is the fence that rises and falls against a completely blurred background. That adds an interesting rhythm to an otherwise static image.
There is a surreal quality to this that I like. The lens has a lot to do with it as well as the processing. With another image in this treatment, I might think you went too far, but for this image it's perfect!
Images of signs can always be tricky. What makes this work is the environment - particularly the background. I like that you placed the sign perfectly against the horizon and lines the pole behind it up with one of its own supports. Well done!
