Personally I think you captured the desolation of winter and its effect on nature very well, the textures are really good and the choice of B/W over color does increase the dramatic features of the image.
as for color, I prefer to shoot bales of hay during summer time, the freshly cut short strands of hay left on the feild (of color green) with a low lying sun, usually brings warmth and life to such items.
Kudos on the picture, very nice !
