the skeletons appear to have some sort of decals on their heads and prior shown undead at have the normal racial hairstyles.
as for Nivv i gotta agree, the hairstyles of the lizards realy dont mesh well with the way the heads look so i cant realy see myself going with anything but the default spines.
I also dont see any head realy beeing good looking other than the default one that all the lizards got and the pachycephalosaurus one which also has teeth clipping through the mouth for some reason
