Salmon Woods is pretty close to the look of New England, I guess. You could change the lots and houses to get that more "salt box" type of vibe.
Change some of the clunky rabbit hole buildings into those quaint looking shops you see near the waterfronts. Add in a few trees that have more color year round and boom...there you go! (I do not care for the color of the roads in SW, but that can only be fixed in CAW.)
Now I'm getting ideas :wink:
