Lovely! And the skin recipe is definitely good!
For what it's worth, I start with a ruddy khaki, shade with a brownish glaze and then gradually highlight up from the base colour by adding more ivory. It produces a more natural skin tone I think. That said, I paint every model's flesh individually on purpose so that I get small differences between each figure - not always noticeable, but I like the like subtle variation and I feel it is more "realistic"!
