Peggy,
You can find a work in progress (W.I.P) if you follow this link,

Apologies in advance, as I know you're a professional portrait painter, and I am mostly an imaginative, multiple figurative painter. This face below is still being refined, and has very far to go. Please feel free to say anything you wish.
I will order some of the W & N white after the holidays and will let you know how it went.
Michele,
I am sure someone will do a paint chip analysis of the Turner, or may have done one already. However, as I believe Speed says it, when a painting is done, it is done. However, if I should come across such an analysis, I will post it for you.
