It either is not white enough or it is just not ok, I don't know what the goal was here so excuse my ignorance, but I have seen better pictures, certainly of you so I don't think the "model" (you) comes out as good as she could right here in the same whole setting as it is.
ok... I am impressed by this, and not to sound odd, But this does look like a VERY DETAILED doll face. If it was not for the textures that I can hardly detect in the face itself, I would have sworn it was the face of a porcelain doll. Beautiful None the less.
