I had a similar shot done, but didn't like it. I'm glad I didn't because this one blows it away. I like how the pathway leads down to the priest, then the back wall leads up, then the ceiling leads back to the viewer.
Lovely blue light, and the contrast to the yellows in the wings is great. It feels a bit like the leading lines don't lead to anything interesting - for some reason the back of the cathedral isn't a stop point, and that makes this image a little confusing. I'm not sure that the very low camera angle has helped you.
good the point of view, I like the perspective and there is a good symmetry. I have a problem with the colours, it seems unnatural perhaps too much saturation.
