This image is very nice, I like it. The conversion to B&W along with the grain and vignetting reinforce the feel of a bleak, cold environment. It reminds me of something you would see on a Ken Burns documentary about the Civil War, you just need a few dead yankees and rebels strewn across the field and you'd be there!
The one thing that I wonder is if your horizon is a little higher on the right than the left? Or am I just seeing things?
