While I've not made too much progress on the city since the challenge, I have made a few little changes: (yeah it's in really garbage resolution)

My main curiosity is how well the walk way transition as seen here works:

It is supposed to be a ramp leading from ground level (white) to the top of the walkway (brown). I'm not sure how well it works. I've been considering perhaps altering the colours entirely so that objects closer to the ground get darker as they go down, not sure if that is a good plan though (so for instance the roofs would all be a lighter colour than the ground, but darker than the plateaus or walls which are generally higher.). Keep in mind I intend to do a secondary map of the upper level of the city which would show the top of the walkways and plateaus.

Also new is an experimental park in the top right quadrant of the map and the grey monument indicators (one of which can be seen in the cropped image).
