Need to see Great Hall from the other side but so far it lacks details, design seems primitive while at the same time it is not clear what is going on with courtyard, looks like a mess.
Do we even have entrance doors and if yes, how narrow are those? Dungeons are underwhelming, I wasn't sure I would like switchable room concept (it is LEGO, I can make myself anything how I want) but now that I see implementation I am sure I don't like it, looks too random. If I can grab a new one on secondary market for €100 I might get one just for the minifigs.
Honestly in my personal case it is quite a blow for the whole modular castle system but maybe some other set will change my mind, maybe Marble Staircase Tower will save it?
