Well the most spotable mistake is the eyes.
They are slightly bigger than they should be, it's usually 1 eye width of a distance between the 2 eyes for a human.
The eye shape itself is a common mistake, being more like an almond shape, try rounding the outer corners of her eye a bit, and think of the white of the eye as a sphere that it is when you render it, getting gradually darker as it turns away from the highlight.
And also a bit of the right side of her nose should show. You probably will fix that, just wanted to mention it.
