Here's the original jpeg, which is too blue and cool, and too dark.
I may have warmed it up a bit too much.
This needs some color correction, some straightening, and there's something not quite right with the perspective.
It was necessary to open in Elements to do the perspective fix, and I may again have warmed it up a bit much.
This one has some hopelessly blown out areas, and the interesting column bas relief is not as revealing as it could be.
Cropped out as much of the blown highlights as I could, and brought up the contrast and sharpness, as well as correcting the color.
