I'm going to give my honest point of view. The highlights and shadows on the face are excellent. The hair is excellent. Even the soft shadow where the face meets the hair is excellent. You give form to the forehead, cheeks, jaw, and the chin.
Your use of highlight and shadow puts your work on a pretty high level.This is
only my opinion but you have to be consistent.
Because you gave detail to the hair and lashes the eye brows look out of place because they are only a simple hard edge shape. You drew the outside of the nostrils with just a
line. You expect the nose to be defined using the same technique as the rest of the face. The teeth are highlighted with like a gradient toward the center. You could get the sense that they are angled
out a bit. The earrings 'glow', almost like they are being lit from below. If that's not the case then the shadows should be deeper.
Good job.
