Cassandra is really easy to photograph. Easy to instruct and alway acting normal in front of the lens. She has a very symmetrical facial form with nice big eyes. I've chosen an overall balancing color tone towards the green / brown to emphasize her brown hair and green shirt.
The light source was a Nikon SB910 shooting into a big Elinchrom Deep Silver 125 umbrella.
