Unfortunately, the first I see are the spots on your sensor which you didn't clone out.
Then I see that this photo is very warm with regards to the colour temperature, even the sky is a bit red. Was it the light you had?
The only thing I did to this photo was to crop it, no other PP. I used a CP filter to cut back the glare on the white parts. The spots on the sensor? I think you will find its spry onthe filter as I was standing next to a cliff face with a force 9 gale and the sea next to me.
