After browsing your galleries last week, I don't feel qualified to criticise your work Bishopsmead - but I'll have a go... This is a nice dramatic sunset and the post creates nice foreground interest. I don't see any problem with your cloning of the sand. The 50/50ish horizon split doesn't do an awful lot for me, though it may have been dictated by your wanting to include the full reflection of the post. Also, the post is positioned on the right of the picture, but the sky seems less interesting over on the left, and the expanse of sand a little dark. I wonder how it would look with the post on the left. Very nice shot though. You know that beach pretty well.
