Oh, dear! It looks as if you fell victim to the Tack Sharp Syndrome -- the widely held misconception that only shots that are "tack sharp" are worthy of a high score. You've got great leading lines, and IMNSHO, the soft focus gives a lovely, moody feeling to the shot.
Have you ever tried HDR? This would've been a PERFECT place to use it. The dynamic range of the church is too high for a single exposure. While the detail in the windows is retained, the rest of the image is underexposed.
I have photographed the Duke Chapel :) It seems you used the same podium I did as support. You seem to have lost the color in the stained glass. When I photographed it I had trouble getting the white balance where it satisfied my eye and folks complained that it was green.
Looks like you tried to hand-hold this shot and it didn't come out quite as sharp as it needs to be. Other than the movement, it's a really nice picture.
