As requested, I'e had a quick look through it, I've never seen the building and know nothing about it, but from a cursory glance: 

"This facade is probably more Spanish than English in its overall composition, being somewhat like that of Burgos Cathedral, but without its spires." No, it's not! What's Spanish about it?

"It is rather wide for its height" In who's opinion? It's proportions look OK to me.

"During the 16th century, the space for cathedral services must have been very cramped.[citation needed] This necessitated a rearrangement of the cathedral's furnishings." Did cathedrals have furnishings (beyond an altar and misericords etc)  and if they did what were they? I don't see why they woudl have made the cathedral cramped - pews etc weren't around at that time.

"The tympanum of the arch is an empty niche." It is entirely an empty niche or does the tympanum contain a niche?

"The second remarkable feature of Bristol Cathedral..." Are we qualified to grade architectural elements by importance?    (talk)
