As leading lines go - that's 'standing room only'. Like it or not - your eyes *will* go to the cathedral. 'Probably best I don't visit there - I'd go broke shooting that cathedral.
I really like the composition, tones and colours. It is interesting that you exposed 400 ISO film at 1/125 f8. It seems that should be about 3 to 4 stops overexposed yet the Portra 400 handles it so well.
I intentionally overexpose by about 1 stop, but have not tried so much. It seems I should!
