I think the 1rst woman seems to be sensitive because she has fine hear, and also she seems to be talkative because she has thick lips.
The 1rst man I think he is very short-tempered because he has the eyes very close together and also he migth be moody because he has two sides of his face diferent.
The 2nd woman seems to be cheerful because he has a real smile so when she smiles her eyes make a line.
The 2nd man I think is sarcastic because he has a big upper lip, and also he may be not sensitive because he has not fine hair.
