It's a very pleasant, relaxing image.
By way of critique I would lose some sky and add to the foreground for two reasons;
1. The horizon splits the scene in two.
2. I think more of the hay rolls, or whatever they're called(
) would add to the forground interest.
I think a bit more contrast would also enhance the shot.
On the plus side I do think the conversion to mono works well and the angle of the hay rolls ( :icon_redf ) lead the eye beautifully to the well positioned tree in the right third.
Very nice shot.
