Number Three Pigeon Street in Baldur's Gate is coming along nicely. It takes a lot of time to hand draw the maps, but it's the only way I know how to do it.
I like to take my time and to go slowly. As I do so, it gives me time to think a bit more about the location and the description of each room.
If you are interested, the original map from Loviatar No. 1 can be had for a fin. All proceeds to support the humble rag.
