Wow, this looks so Mediterranean!
Maybe, as a suggestion, also add a couple of tiles with shops/restaurants-graphics in the foundations.
To go alongside the umbrella's.
Something like this from Fridaemon's objects: But just something simple, like a couple of windows in the foundations, thats already enough (the awnings like in Frideamon's objects are not necessary)
Your foundations already have the darker arches, just swap the lightbrown insides for some windows.
