Cahokia/Illiwek could use a little texture on the top of the hair on his head. The non shiny texture should help that but try for more detail of the hairs.
King Kamahamaha is Looking Good SOG... Perhaps the facial "nubs" are not needed. It seems a King would either have a beard or shave but regardless, the "nubs" seem a bit too straight line as if shaved above the lip and cheeks unless that is what you intended. On Four, the Shoulders seem too large for his neck and head and would look more natural if slightly narrowed.
