Well just off the bat I noticed the following:
Features:
Pub, Corner
Shrine, Corner
TNO House 1-3
Groups
Bridge between Houses (Beautiful feature BTW)
Small square
Arena
Plaza
Though for the life of me I can't figure out how you managed to get that little waterfall in the second picture there between stairways.
You found nearly all of them except for a feature (construction site) and a group (estate 4).
The TNO houses were experimental and I won't use them, but I left them in.
Building the waterfall has to be done in a specific order because it would have taken dozens of new tiles to make it possible to build it in any way people can think of.
You have to start with cobble terrain, then raise it where you want it to be raised. The next step is placing the water terrain, first on the lower terrain then the higher terrain.
After that place buildings on the lower terrain then the higher terrain (always build from the lower terrain to the higher terrain).
I also made some tiles just so placing these waterfalls is possible. As long as the waterfall isn't finished with buildings on all sides, gaps will appear between sides that already have buildings and sides that don't have them. This will change when (if?) I make it possible to have wider waterfalls.
