As to the environment, I modeled every object separately and then imported them as references. I wanted to find a good camera angle, similar to the one of the drawing. In the end I decided to turn the wall on the right side about 45 degrees to have more space and get a nicer shot (Fig. 02c & Fig. 02d).

Texturing & Shading

For texturing I used the 3DTotal Textures collection. These textures are amazing and it is a huge library! Many times I just started browsing through them without any idea of what I was looking for until I found something that fitted the scene.For the wall I took the base layer from Total Textures V01:R2 – General Textures ", some dirt from Total Textures V02:R2 – Aged & Stressed and Total Textures V05:R2 – Dirt & Graffiti and mixed them in Photoshop following the UV layout (Fig.03a).



I then did the same for the tires (Fig.03b).



For the sky Giovanni started with a base from the Total Textures V15:R2 – Toon Textures and continued adding details, painting clouds and little planets.

For the car paint and tires materials I decided to go with layered materials. This gave me the ability to add dirt, scratch and all the little details I wanted with minimum effort. The textures mostly came from Total Textures V05:R2 because they're full of dirt masks. After importing them into Photoshop I reduced the details to make them more cartoony and I made a lot of masks to control the layering.
