Yes, Zackman, due to some of the detail options (which options unknown to me) the face of the toon-in-progress is "void" or pitch black. I am able to guess at the outline of the face shape and hairstyle. When the face is void I am unable to select any detail options, or no details at all.
The one toon I allowed to enter game with "black" face has tattoos I do not recognize from the available options. She has several shades of brown with what appear to be layers. I have described it in starter post as multiple options piled up. Certainly is a unique look.
