The Face

It serves to definitively specify a character. It's the who. It makes it so that in a vignette, seeing only the face, we can tell which characters are talking.

When the viewer sees eyes and mouth, he recognizes a face. The nose, the shape, the type of eyes and mouth serve to concretize. It makes it so that there is no doubt about the information regarding a specific character.

How far do you have to go to define a character well? How much information is necessary for the viewer to differentiate between the characters?

That's something that needs to be defined.

If it is a generic face, without special and specific features, we will once again enhance the identification by the reader. We will make it a common name instead of a proper name.

The face, like the form, has another type of information. It is the one related to action. He talks, he cries, he gets angry. It's more concrete than the silhouette. Less subtle. More explicit and more direct.
