Test Shots of Actors:

We took test shots of Alice to see how her hair and make-up will look when filming.
Connie: Hair & Make-up
Kieran: Photography.
This is the hair and make-up that Alice will be wearing. See Costume design for reasons why.

The reason Alice is pulling the face she is, is so that we can see what she might look like when she is in character. Because the character is rebellious we want her to look dangerous.
