Porcelain

I can see where you were going and it turned out pretty interesting. The stare is definitely doll-like anyway. My impression of porcelain though is that it reflects somewhat colder. I think if you turned the saturation down on the skin a bit, adjusted the colrobalance a little more towards blue further from yellow and added a hint of brighter highlight on the forehead and cheeks (porclain is more reflective than skin) I think you'd get a more doll-like quality.
