I agree with Calunio here, this map is gorgeous but there is a lot of open space toward the bottom. Perhaps trimming that down, as well as a tile behind the bar, usually bars are pretty close to the wall.
Map looks fine to me in size. If anything, it looks a bit small, but I would definitely say add more things, I hardly see any details. I suggest adding a rug somewhere, definitely a few pictures on the walls and maybe a shelf with books or whatever would make sense to the map.
