A truly beautiful space to spend hours upon hours looking, reflecting and seeing. You have some well-executed photos here
To offer feedback, other than platitudes for good work done (and done well), it might be helpful to know what your goals are. For example, a couple of your photographs appear to be record shots of the outstanding architecture and sculptures. The second one introduces some atmosphere with the sunlight streaming in. In your full collection online, it's nice to see some larger views that include the floor, for example, to introduce scale and the idea that this is a complete building.
Two things I notice, however...
I'm finding that the perspective distortion created by pointing a camera upwards with parallel lines reminds me that I'm looking at a facsimile of the original. Because of this, I'm not drawn into the photos the same way I might be if the distortion was corrected or reduced. Some would disagree, no doubt, as they might see the distortion as a reminder of the soaring nature of church interiors, but I'm finding it mildly distracting.
The second thing I notice, and my cathedral interiors suffer from the same malady - a church is not the building, but the people and there are no people in any photographs. I know this is perhaps tangential from your goal of capturing architecture, but even a few shots that include people in some way would go along way towards illustrating the essence of the space as a people place, instead of simply capturing cold stone. I'm not a people photographer, but I recognize when spaces, particularly in the built environment, seem somewhat empty without people.
Just some thoughts. Take 'em or leave 'em.
