I find female head 5 too childish and head 1 to have the features oddly squished into the middle of the face, but the others are okay.
Different heads for different character types, simple as that
It is much easier to roleplay a "gifted" 8 INT dwarven magician when she/he has a childish face. I will be glad if they add more heads, but I am against removing the old ones for them being not beautiful enough or smth. Because beuty is a stretch on its own, can matter anything to anyone... But I am happy that the game allows me to make some vile looking creeps like this gentleman
