This was towards the end of our shoot. I asked her to put on blue eyeshadow really poorly and bright lipstick and smear it over her mouth area. Then I asked her to hold the flashlight again and to make whatever faces she wanted. Towards the end I asked her to make the faces more sensual in nature and the last 5 or so are dynamite and what I was going for, but sometimes you don't know until you shoot/see some other stuff as you go through the process.
