Let's take a closer look.
Take a look at the each person's face, they are not all symmetrical.
It is as if the younger, smaller, and babyish they are, the more symmetrical they appear Try taking a look at the line of ones nose, it is not symmetrical.
If it were absolutely symmetrical, it would look very unnatural and unusual.
If it were more or less asymmetrical, that is, a face that is not totally even/equal, then and only then would it seem normal
This perhaps reflected each persons life!
