For me, I would like to see just a little more, or none at all, of that interesting looking house on the right.
That little glimpse of the house makes me wonder if it was possible to shoot at a landscape ratio and show more of the overall scene. But there may well be some distracting items which you didn't want.
The shadows are possibly a little on the dark side but I would rather accept this than mess up the sky colour.
Maybe I went to dark on the brightness/contrast adjustment... I think I was probably influenced by the shiny area at the center of the mill, which I didn't like very much.
Philip, your tone adjustment looks closer to the original condition of the pic, before I messed up with it.
I didn't want it to looked "washed out".
I'm wondering how it would have looked as a horizontal shot? (to reveal more of the setting that it was in)
