oh well okay then
you should use in-game screenshots of the game to build it to literally look like the game
hong kong isn't just a compact bunch of streets and sectors but rather wide open with intersections, winding streets, and tons of little details
even adding bike rails on the sidewalks would help aesthetically
the buildings could use windows and stuff
if you don't want players to go inside you could just make them float up against the side of the building with invisible bricks just to give the aesthetic effect
also, there's a lot of storefronts and neon signs too
you don't have to model it exactly after the place in the game but you could at least make it feel like you're in the place when you play
