I'm 3D modeling a version my own concept car Inspired in the american muscle car design. I also want to recreate the style of the car illustrations made with airbrush; I found one of this illustration in an airbrush book and I did it in airbrush in my college years for a "presentation" course.
Initial sketches.
Here are some of the initial approaches playing around with the 3D software:
Front Camera
Back Camera
The style or expression objective is to reproduce that "airbrush" feeling using the cel shaders from 3DStudioMax.
