Color:
Do the colors look accurate? I think they are slightly off due to soft lighting.
Composition:
I key element in this shot is balanced. As I look at the photo my eyes are drawn to the subject.
Format: Does the Horizontal or verticle format fit the subject? Yes
Point of view:
I think that the point of view for this shot that you chose is the best way to view this photo. Might want to crop out the sides a little.
Overall this is a good photo. I think the stain glass adds a bit of fuzziness to the shot. I think a good soft softbox light would enhance the view and also would dramatically add to the boarders on the cross.
O.K. religeous bias got me at first, scored this a 3. It is better than that, but this only fits the challenge because your title forces it into that nitche. Tad of glare from the lower right corner of the circle (either all corners, or none) Fine photo, but the best I can go is 5. Swash
