Illustration made with Blender and Procreate in 80h.

First, I took some screenshots from japan streets in Google street view.

Then i fixed the perspective in Photoshop, reajusted the colors and composition and ad​ded some personalization. 

On blender, I mapped those images on cubes and modelised them in order to follow the shape of the facades. I added some props i found on Sketchfab and some buildings from KitBash3D in the background. Some lighting and a little atmosphere.

And here is my final render, before painting over it in Procreate.
