Fantastic! But that clock....
I've read through each and every story and I love it, with 'Mums the word' being my favourite.
(Although the only lights that should be on the Westminster Clock Tower often known as Big Ben should only be the clock itself. But don't take it badly, i'm fussy about London architecture :P)
I love the style of the closer and more detailed backgrounds!
Those lights must be a procession of lanterns carried by students of the Invisible College headed to their next ghastly lesson, beckoned by the silent ringing of the bells.
