By the look for the buildings in the background I guess this is a church window right? Good example for the glass challenge, everything is in focus. Good luck.
Could the cropping have been a bit more even either side of the window? I would have prefered not to see the reflection of the people. NIce choice of subject.
A wonderful leaded window. Your composition doesn't help it much, It isn't angular enough to look planned and not straight on enough to rule out the possibility that you took it at an agle on purpose. With this much confusion I have to go it a 5.
