Wow. I really like this photo. The colors are the first thing that hit me. It sets the mood. Then, the textures caught my attention. The only thing that bothers me is the background sky surrounding the cross. It looks a little artificial to me, but that's after staring at it for a solid minute. If I saw this framed on someone's wall, I probably wouldn't notice.
Did you use filters on the camera to achieve the warm tones?
