Hi @Ralph Lear . Cool photo, but I would agree with you that the issue is at the top of the fence, especially on the right where the dark cloud is. It looks odd to me because the dark cloud just ends at the fence top and doesn't carry on behind it through the pickets of the fence. The sky edit also seems to take away the sharpness of the top of the fence.
Looks a lot better, but still not perfect:
Here, I have the impression if part of the rope is missing (may or may not be the case):
Great to hear Ralph!
