As for the 2050 city scene, I made the concept that the road was wet by the artificial rain. Because I heard that the sandstorm break out a lot in desert area around LA.
To create a future city with differentiated atmosphere, I set 3 combination sets of colors Orange & Blue, Green & Red, Pink & Blue as main lights colors for each scene.
The reference is Francesco Lorenzetti's LA Cyberpunk.
