Thanks for the suggestions. Yes the roads are going to get some lining as is the water. I don't have a great solution for the transitions between colors yet but definitely needs to happen to keep with the look, even if its just a more smudgy style of blending to keep with the style of light and shadow on the rest of the map. I'd love some idea if anyone has any. The cartoony details got away from me a bit as I originally was going to make the map mostly about funny labels and the like but the theme developed so I went with it. I still need to find a font I like too. One of those projects that keeps expanding exponentially.
