Nice skintone. The lips are looking better, too.
Couple of problems with the eye. First, the highlight seems like it’s on the wrong side. The light is coming from the upper right, the highlight off the dome shaped cornea should be on the upper right. Well, actually a bit closer to the center, because of the dome shape. Second, the large highlight indicates a lot of light shining into the eye, which would make the pupil contract. Most people’s upper eyelids lift to uncover the entire pupil, or higher, unless they are blinking. What I’m saying is: the pupil looks too large. I’d suggest drawing a pupil that just touched the upper eyelid.
You might also try making the lower lip color extend a bit wider than the upper lip color, so the upper lip looks more like its resting on the lower lip. As it is, the line extending to the corner of the mouth reads as a cut rather than two surfaces.
Overall, a huge improvement over the earlier image.
