I dunno, doesn't seem that bad to be... I mean, it's not like me or Boingo would make it dark and gritty. In fact, I decided to kind of switch things up from what you'd expect and have the asylum look nice and sterile. (Like in the pictures) Though, in the end it's really Boingo who will decide how it'll look really I suppose. Still, I'm staying away from the whole flickering lights, horror style you usually see.
On a semi-related note, I'm pretty proud of the 3D floors that I have in use in part of the map that's not in the pictures, even if it isn't really that special or detailed. Mostly because it's the first time I've used 3D floors.
EDIT: Finished most of the map layout:
I took some story liberties and set it on an island ala Alcatraz, hope you don't mind.
