The hexy bit (wizard city core) looks clearly planned and built in a single phase or two. So that seems legitimate. I think the scale seems about right. Also the hexagon is an efficient shape within nature btw so I guess you could play on that too if needed.

I'm guessing the port bit is a more natural settlement given the layout built over a much longer period. I imagine there is an "us and them" attitude between the two "districts".

You could have many of the poorer people living in the PORT district. Many of them might run rickshaw and similar services for those in the core wizard city. Something like that.

And yes, I guessed the capitalized names were placeholders until you picked proper names.

Don't forget sanitation and water. Is there an aqueduct and sewer system or the like? That will affect the character of the city.
