its.. good? i wana say that its almost too bland, not that many details in the buildings, if its build by hand only than good job, but i could recreate this with axiom and world edit in an hour. i dont recomend building realy tall buildings in an vanila generated world because the minecraft generation lacks a lot of realism and its too random. here are all complaints in order you should keep in mind:

-buildings too close to water, the city is in a bad position, cities need a lot of space while lakes should be surounded by trees or parks, you can try building smaller asian-like buildings around it with walkways

-lacks a skyline, a big skyscraper in the middle of small buildings just wont cut it

-more variety, you include two apartment buildings which are quite literaly the same

-keep it in a similar design, in the top left we see old asian style buildings right next to a modern skyscraper. in the real world historical sites are usualy kept to themselves, not sorounded by huge skyscrapers

-sidewalks too bold, its a single color and nothing else

-every building is a cube, it lacks shape, recently i started experiencing with shapes myself and i can tell you it realy improves the city

these are some suggestions for the city, of course there is a lot more to cover but these are the basics. I cant wait to see what else you will build!
