ok lets nitpick.
1. if it was realtime lighting then the eyes would NOT have EXACTLY the same reflections but reversed, smacks of optimisation to me... ie - its not lit its just a high res texture for the eye.
2. if it was realtime shadowed then unless it was a loreal advert you'd see more self shadowing especially around the nose area, seems the gradients in the skin we are seeing are more than likely part of the skin texture itself again leading me to the conclusion - its not lit, its a high res texture.
3. the eyes have a shine in them as if a light was directed towards the character yet no other part of the face belies any form of directed light...
my opinion would be that its a MAX render with a high res texture and little or no advanced lighting, probably a mock up of what they WANT rather than what they have. The silhoutte does not provide any visual cue's as to the poly count which infers that the poly count is VERY high indeed - PR shot high in fact.
The texturing is VERY good, the eye brows look nice but does that detail look as good from the side profile... doubtful and therefore damning when the effect falls down when rotated.
