I had turned up the saturation quite a bit and the original was slightly underexposed that had to be compensated. That might have made the sky look artificial.
I did crop the sky and tone down saturation and am including the modified picture.

I understand what you mean by 'move back to get more foreground and less sky', but I don't quite understand what you mean by 'move left to shoot on a diagonal'. I will take it to mean that I should try to compose to find diagonal lines in the picture. My first instinct for that would be to move right so I can get the lighter stone lines to be diagonal (bottom to right).
Here is the new crop:
