...Shame I couldn't get any photos inside and that it was a fairly overcast day

A nice ancient place you photographed.
Only one remedy for an overcast day...returning in better conditions 
Or...pasting a fake sky in it...
There is perspective and there is perspective...in the images above it looks as the cathedral can fall any moment.
I think certainly in "architecture" this is of great importance. Until yet sensor and lens have not the same possibilities as human eye and brain.
When not possible to step back there is quiet some software to improve perspective.
I gave it a try with Corel PSPX6 and this is the result. LINK
More realistic or not?...Up to you.
There is so much I have to learn I'm affraid never getting old enough
But it is challenging and lots of fun.
Should you have objections concerning the link or comment...please let me know and I remove it.
