Very, very nice MOC. I was admiring this last night but was too tired to comment on it (it was about 2am)!
The first thing I noticed was the very inventive technique of the men holding balls - if you look in Lego Batman: The Videogame on the flying levels you see a few of them too, and including it in your MOC really captures the spirit!
The exterior looks magnificent and the interior is brilliant too, I love the cells! Great narration/tour also.
Only one irk I have about this - it looks a little too tall, I've been in castles that (if to scale) would not be so high as this. I know it's meant to be a big building in the comics, but it just looks a little odd, not too bad though.
An all-round well done though, this is a masterpiece!
