The cloud throwing the distant bales into shadow really doesn't detract from this at all for me - in fact, I think it gives some quite nice definition between the foreground and background and adds some depth to the image.
However, something just isn't sitting quite right with it and I think it's the composition and framing that are bothering me:
The first thing that catches my eye when I look at this is the very strong line of the 'furrow' leading off from the dominant bale . . . I really want that line to lead me further into the image, but instead it takes me right to the far left and then peters out.
When I take my attention back into the picture, I'm then grabbed by the second nearest bale over at the far right. I think because it's more side on than the main focal bale, that strong geometric circle shape is grabbing my attention and it's fighting with the closest bale to be centre of attention - especially when you look at the way the sun is lighting up that circle and giving it a golden glow.
Taking those two things together (leading line taking me to the far left and the bale fighting for dominance on the far right) I'm left with the impression of the image being quite claustrophobic and feeling like it's been cropped too tight on either side.
I really want to look at this and get a feel of space and wide, open fields but that's just not happening for me with the current composition.
Lovely location and lovely light though - if this is somewhere close to you, I'd love to see you go back and try again from a different angle and perspective because I think that could take it from a 'nice shot' to something a bit more special.
