Very nice city, and I dare to say that you tried harder than the last times,
regarding e.g. the amount of time invested into executing that esplanade/promenade
One suggestion was to use some pedestrian path mod by uokiok, you will be able to have
ped path stairs, rather than just ped paths.
Transportation - Uokiok - Pedestrian Paths - XXL | XLNation - Cities XXL
Others then that, your city looks very interesting.
A last suggestion for the streets in a very hilly area.
I know that you cannot avoid any slight ups and downs of the streets,
and that it is hard to place streets over the water,
but you for instance use both of the following options:
1) for the hilly parts, use first Over Water Roads by pharmist, they should work also
in XXL, at least from what I heard in another thread, otherwise ask someone before.
When you directly connect two streets, those over water roads will ignore the terrain,
i.e. there will not be ups and downs. When you then have made some grid with over water roads,
place some water plaza or greenery plaza (NO absolutely flat texture) within the frames that you got
by the road grid. And afterwards use normal roads and replace the over water roads from intersection to intersection. Afterwards, replace the plazas, and place your buildings there.
2) for over water parts of streets, you again use over water roads first and connect two streets with each
other, at best at same height. Then for that rather long over water road part, make some intersections
about every 20m of that road, i.e. place some small over water roads there.
Afterwards, replace the over water roads with normal roads of same, again from intersection to intersection.
It does not have to be a road of the same width, but that would help when the roads is not a straight line.
One note: when it is a curve over water, delete the small roads of two intersections first, then place the normal road in between. When it is a straight line, you can delete the intersecting small roads afterwards...
I hope that was clear
