Sounds reasonable, and interesting. Sounds like there's a history to the city that maybe isn't entirely pleasant? borders are hard, especially for such a nice hand drawn map - don't want to lose the map itself in the border! The handwritten font lends a nice touch to the map, and keeps the focus on the building shapes. The stain is a little dark, and it looks 'heavy' enough to have made the ink run. I wonder if perhaps the "border" you have now is just too wide? Perhaps a thin border that mimics the alternating black and white scale markers would look good if it was in the same hand drawn style (maybe at a reduced opacity, too). Sorry I don't have an example of what I'm talking about! But overall, this is looking great.
