For the skin, I don't think it's enough just to shade/light the outer side (near the face frame). You can either practice the beforementioned blocky shading, or the softer ones like my favourite artist 15 do (check one of the work at here). Anyway, try to be braver at shading etc for the face.
Nice job on the eyes! Though like N0UGHTS mention the positioning of her eyes are still not parallel. Anyway, keep up the good work!
