The setup is simple. From the basic Shader, use a ramp for color. This is where you will give more or less "light" to your shader.

Then we use 2 internal textures. First, and not necessary , a Cloud to create irregular scattering for the shadows.

Then a Wood with custom ramp color. You can change the size to add details. This texture influence the Normal.

Then you can finally use Edge option to obtain a contour line. Edge is fast to render but can't be setup in a complex style. You Can use Freestyle for a better contour result, better but slower.

 Enjoy!
