It looks OK.

I'm very good at cities, there are my suggestions:

• Make small and many houses
• If you want to show the inside of each house, try to design the interior by making chairs, tables and such and try to make everything inside small.
• Try to only include buildings in the shape of houses.
• The ground should be made of a mixture of dark (or bright if you prefer) powders (just put everything inside a huge container and use pressure and positive and negative gravity to make a mixture off of it).
• It would be very very nice if you make the city a big island in the middle of the ocean (it would be more nicer if you add one boat with a small smoke particle coming out of it and make sure there is an invisible void to remove it when it reaches a certain distance).
