The upper bit looks like she is trying to help someone down there which implies herself in the old time but at the same time, she does't like the old her who was always told what to do. The shadow of her hand is like a gun, which implies saying goodbye to old times. She is chasing her dream now and feeling free. The downward bit implies the period when she had no clue what she wants. The lighting enhanced the emotion in her eye. I want to create the contrast as she becomes quite different after coming to UK.
