4 is by far my fav. nice winston churchill face. for 3 i agree that mom is in an in between zone where she's a supporting role (literally) but not really a part of the image. however i think this image would be better with more mom rather than less. in 1+2 the green saturation is heavy and dominates. i'm normally a saturation whore, but this is definitely a situation where i'd really pull some color out of the background.
Paint over it with Robert Palmer Girls! They are the solution to all photographic problems, ultimately.
