I really loved this woman's confident and slightly mischievous smile: there's no airs and graces. She is just being herself. In the sketch below, I thought the woman had lovely smiling, hooded eyes, and an interesting smile: a wide smile, but with closed, almost pursed lips. I used a Prismacolor Sepia pencil and a blending stick for both of these.
