Photoshop face study

My first time on Photoshop, Face shape study

As you can see from the picture I have drawn, I have drawn three people in two different ways.
The first row, the man on the left has a egg shaped face with large eyes, and smooth jaw line. I then drew the same man to the right but with opposite characteristics, with a square face with small eyes, and a sharp jaw line.
The second row, the girl on the left has a heart shaped face, very large circle eyes and button nose. This style is more of a chibi anime style. The girl on the right has a heart shaped face, more realistic eyes and massive nose. This style is more of a western cartoon style.
The third row, the woman has a pear slender shaped face, large glasses and pointed nose. The woman on the right has a square chubby face, thin glasses and a rounded nose.

These differences are small yet it completely changes the characters personally, clothing and body build. With a sharper, slender face shape it would suggest a more posh, high-class, grand sort of personally. And with a square, wide face shape it would suggest a more strong, protective, intimating sort of personally. And finally with a round, large face shape it would suggest a more innocent, young, cheerful sort of personally.
