A lopsided look of surprise. She is really trying to raise both eyebrows here.

A big smile.

Trying to close both eyes.
"Ooh" face. Notice how the left side muscles (camera right) overcompensate and pull her whole face to the left.

This is a subtle one (as our friend Mitchell Sargent says, "it puts the B in subtle".) She is trying to flare her nostrils, but the result is just a sideways nose.
