Thank you very much for your comments, I really appreciate them.
Image manipulation came up, so here's a bit more info on the picture. The photo was taken about half hour before sunset, in the mountanous area with light-colored hills all around, and (very) patchy low clouds in the sky. There were a lot of reflections and uneven light, hence the somewhat patchy look.
The picture itself is a sandwich of two photos taken with different exposures from a tripod, one for the sky, another one for the walls -- too much exposure difference to handle in one shot. The two photos were taken within a few minutes of each other.
After the sky was pasted in, some burning and dodging was done to the walls to bring out the texture, and perspective was corrected to straighten out the lines.
Some limited burning and dodging was applied around the cross, but not much, primarily to correct for some overexposure.
It appears that the area where the cross does not have the same lighting on it like it has been manipulated....I love the tones of the stones and the clouds.
