Generate a super realistic 3D view of a city on an island for my city simulation game. It should show a downtown view of a city criss-crossed with a regular street grid, with cars and people going about their day. create realistic office buildings, police station, fire station, port. Make it look like a middle of a sunny day. Make sure the geometry of street and buildings is correct and rendered in isometric projection. Make sure the textures and lighting of the buildings is realistic. Add palm trees and some parks.
