I have changed the top painting again, I wasn't really happy with the previous results, and also added the last details of the back and the sides.

I have changed the color palette on the top since it was not matching with the Overground's main colors, also removed the normal and height map of the top but added a glossy map to it to have the brick texture visible, and finished the main coloring of the Van.

I have been living in London for almost a decade and thought I will use one of the most artistic districts of London, which is Shoreditch.
It is also one of my favorite areas too, which has given me so much experience and fun and which also represent friends, connections, passion, art, and contrasts, not to mention inspiration.

I started with the front part of the van, which will look like as the Overground train that crosses the whole district.
What else could express London's buildings more than bricks...and more bricks?
Here is the top view of the Van:
