I like the perspective but I would like to see this more symmetrical. There is a slight lean to the left as is evident in the ceiling and I would like to have the view of the columns on the left and right showing the same number of columns evenly. The left side shows part of an additional column at the top left. Were you setup on the floor or were you allowed a small tripod?
I see the points that mt-parker is making, but those could be easily fixed with a crop and rotation of the image.
Having been there, I like how you have captured the different lighting levels and the color of the space.
I especially like how you have captured the high windows without blowing out the stained glass.
