Sorry I haven't responded to this thread, but I haven't had much internet access for a week or so. Just catching up now. Personally, I like the original shot because I wanted to focus on the source of the water filling up the road in the foreground. Then I started cropping and couldn't make up my mind. For me it is one of those scenes that when I look at it (depending on my mood at the time) interest changes. I hope that makes sense. In crop 4, I like the mystery of what is beyond the opening where the water is coming from.
Thanks to all who have taken the time to comment.
@mikew What tweaks did you do?
