Could you rectify and crop the colour version so that only the window is to be seen? No wall, nothing else?
Of these two, I like the first better than the colour one, but the colour one has "potential for play".
All in all I am surprised to see the illuminated window from the outside part of the church, I have so far always only seen them when I was inside a church... but I have never seen any beautiful stained glass window at night so far.
