Hello Nigel,
My very personal view/impression:
Both pictures work very well individually. As I have never been to this place, I have difficulties to obtain a visual connection between both pictures. The titles and explanations help me to make the connection, this is good. I am now thinking if placing both next to each could make a difference.
The other possibility could be to transform the first in b/w and keeping the color in the second (if available).
Just a few thoughts.
Thanks for showing!
Best regards,
Michael
