I need a model for my art project. (a picture)?

For my art project, i have to include all of the 7 elements. im doing oil pastels i think, and am drawing a teen aged girl, maybe 16 years or so. she will look sad, but i want her to be the most beautiful girl. dark hair, pale. (NOT SCENE) could someone give me a picture of a girl of that description? she doesn't have to look sad in the picture but it would be easier. also, she will look deep in thought. THANKS!
