I do not like the darkening of the sky at the top of the frame. The darkening looks a bit contrived. I think I would leave it full-frame, as shown, but go the opposite way: go for a very LIGHT, bright,dreamy, ethereal effect on this shot. ALmost a soft-focus, fog, or dream/diffusion filter look. If it's not all that clear, and maybe has some missed focus, then why fight that? Why not go in "the other direction?"
