I do like this kind of shot, and this is a good spot. There's some nice pattern and symmetry, and good textures. (I would be tempted to not bother cloning the blemishes out for that reason - but that's just me
My main thought as far as improvement is concerned is that you have lots of different shades of blue, which aren't quite different enough, for me. I think you also need to make the red 'ping' a bit more (for want of a better technical term. Just a tweak in levels and a curves adjustment should do it (see my modification). I think it darkens the sky enough to give you a bit more contrast.
I've also cropped in a bit to give the diagonal lines a bit more emphasis.
Hope you don't mind the suggestions - just my opinion, of course.
