Your light is a little harsh, deepening the shadows under her eyes. Maybe if you'd waited until the sun went down a little bit more, and softened the light.
Lighting is a little harsh on the side of her face. Considering, you did a good job of showing detail on the far side. Shadow around her sunny side eye is distracting. Good luck in the challenge.
