Good shot but no real point of focus. Window neither interesting enough nor can I read the wording on the right. Might have focused more on the wording and left window to the side.
I am making two passes on this Challenge. I will vote on your photo then return later(before voting is over) to comment on what I like and dislike about your shot. You can take the comments however you wish and I will try not to be mean. Just don't take it the wrong way.

The reflection on the wall kills it.
The color in the stained glass window is excellent and not overpowering, nor is it oversaturated. If the letters on the right hand side could be more clear, it would add to the image, but that is one of those things you can't really control
