There are about two dozen portraits here.

Some of them are characters from various Castlevania games, others are generic background characters from My Little Pony.
You can just ignore the ones you don't want.

Yes, i realise that many of them aren't fully arsed. That is to say that they're half-arsed. Whatever. I'm not redoing them.

You know how to use these, right? Extract them all into:
Documents/Almost Human/Legend of Grimrock 2/Portraits

Oh, and don't mind the OC. Didn't have the heart to take him out.
