Brilliant! Very nice layout...would like some back story and if I may suggest. In those big white plaza stretches...perhaps consider creating small pools or organized grassy areas within those plazas using the ped paths...seems to be almost too much plaza inbetween those roads IMO.
Nice city!!! Like the road layout!
At parts you could decorate the area a bit more,
e.g. the port area would deserve some more chaos, this way
it would look rather natural, but that are just minir points.
Wise composition of skyscrapers in the CBD!
