Are you talking about the dots/blobs on the lower portion? I actually think they add something to the map. Maybe makes it look more 'lived in' if that makes sense? I'd tell you to add more and see how it looks, but you can't go back if you don't like it, haha. That's why I don't play in the big boy league of pen and ink. Maybe add some more blotches in photoshop and see what it looks like?
