When a character's face is on screen but is barely visible due to some kind of obstruction.

Such examples include:

• Clothing (mask, hood, helmet, etc.)
• Body Parts (hair, hand(s), other people, etc.)
• Environmental Circumstances (objects, fog, darkness, etc.)

Not to be confused with:

• faceless_character - The character's face is off screen or not drawn/rendered by the artist.
• faceless / featureless_face - Characters with literally no face.
• shadow_face - The character's face is a dark void with almost no features, usually only having eyes and/or a mouth.
