I did the links to neighbours from experience of constantly having to look them up last time in GuildWorld. I will try to get some semblance of a picture with neighbours WIPs edited in before I start mine. I gues I will have to put something on canvas tho to help them plan theirs too.

Anyway - Yes I like the 3D thing. I have something a bit like that in my area and your image makes a neat reference to wrap my head around it. I was wondering about how much undercut to apply to below the edge. Theory says that it would be a straightish drop for a straight river but would undercut the outside bend if the river curved. Not sure what to think tho. On the other hand people could have been chisling the wall for centuries so I suppose anything goes.
