This is my first experiment with "The City Generator" add on for Blender. I then used "Weather FX" addon to add some rain. Finally, I used the "Procedural Crowds" add on in Blender using the Follow path crowd settings.
I rendered the 300 frames @ 3840 x 2160 using Eevee with DOF, volumetric fog and motion blur and it took 10 sec per frame to render. I also did a little color work in After Effects and added some sound effects and music from Storyblocks.
