I've not used campaign cartographer, is it possible to put drop shadows in on things with it? It looks like the walls have some, but it might be nice on the stuff, too, to give it more perspective.

Also, is there a grid on this? Is that why some of the floorboards appear to be bisected?

I think it looks pretty good for the most part. It's definitely better designed than any tavern I've attempted, mine always end up looking stupid
