I really like what you are going for compositionwise in your #3 here, though I feel it is lacking a bit ... you might have wanted to give the top bush a little more room and not crop its top tips off. The lines in the field nearest to you only really begin a little higher up, so you had room to move the camera up a bit and not lose anything important in the foreground. But all in all I like that long-lens effect here!
I also like the close-up of the barn wall. Reminds me of my pics of This Old House in Neulietzegöricke where I also decided to go very near and get a very sharp photo.
I assume they originally all are colour photos, converted?
