Hello! Oh boy, is this one right in my wheelhouse. Honestly, your sculpt is looking really, really good. As Omar said, hair can help a lot. Adding even some temporary hair to establish her hairline will help you “see” the likeness a lot better.
What helps me a LOT though is getting away from the gray material or matcaps. Create or find a skin material. You don’t really need any sort of detailed texture at this point, just a skin material with a realistic level of subsurface scattering. Toss in some lighting (I usually just use a studio HDRi…I think it’s from PolyHaven). I usually also add a simple plane with one edge extruded up as a floor and backdrop.
Run a test render and you’ll probably start to see where the likeness succeeds and what needs more work. Again, I think you are pretty spot on here and it will probably not need much adjusting at all. At this point I’d start considering a retopo and establishing a basic texture…then on to multiresolution for fine detail, etc.
