Sorry, I didn't mean to be bossy. I couldn't hold the details of your face in my memory so I could compare it without seeing your picture again. I have all three picture on my screen now and I can compare them.
I think you do look a little like Drew Barrymore, but I think you look more like this picture of Denise Richards.
Drew Barrymore's eyes have almost the same shape as yours, but Denise Richards has the overall shape of your face, your nose and your mouth. She has your cheekbones and your eyebrows are the same shape as hers, although hers are heavier in this picture. I can't see your chin and I can't be sure about your eye color from this picture, so I can't comment on them.
Edit: Denise Richard's picture I used for comparison did not show up, so here is the link for you to cut and paste in your browser window:
