Bill,
Some nice shots here, like the fence post too.
One thing you may want to consider is the horizon. It is tilted in a couple of the shots to the point of being a bit distracting to me. This is easily corrected in most photo edit software. Of course nothing beats shooting it level to begin with; but, alas, I find myself homing in on the main subject and forgetting the details.
How does that go? The devil is in the details?
I think polyvios is asking what is the exact process you used to get the black and white photos. Do you have a B&W mode on your camera for example? Or did you convert a color shot to B&W in Photoshop or similar software? If so, what conversion technique did you use? Stuff like that.
