Beauty Shot from Unreal with some Touch ups in Photoshop

This is what the model for the final shot looked like at the end. Notice that the normals on Gohans Face are forced into certain directions to create the anime shading. The Backdrop are just some planes on top of each other.

This is what the model looks like with flat colors applied.

The next step is to draw lines onto the model, I tried to stay as close as possible to the anime and the source material for this shot.

Afterwards I created the outline by duplicating the mesh, inverting its normals and transforming it outwards by its normal direction. I changed the distance to the base model here and there to create some line thickness.

The next step was to create a separate texture for areas of the mesh that should always render as shadows. It allowed me to define further how the shading should look like.

This is the final shot, after some touch up in Photoshop.
