A new challenge: black tint in white paper

Black tint portrait inspired from F. Clouet

A few years ago I began to draw with new drawing technic called Japanish Tint, ever with my first work was necessary  to run an adquire the materials like a black tint called Chinese tint in my country.
But the vendor only had Indian tint,he said - the purpose is the same only the manufacturer changed-
Well the product was fine and my challenge was to get a new clasical work, then I was reading a old art book with clasical sketch portraits in sanguina, the book talk about french art school, and a few amazing images were inside of this book.
I selected one beautiful image from book, the short information only said about the art school but nothing more about the painter, later I had a good look, and I get more information about the painter and the name of the young lady.
I enjoyed this work because, I was drawing with indelible tint or chinesse tint, my work instrument was a pincel #8, soft solvents and art paper...so sweet.
At last the painter was Francois Clouet, and the model named Maria Touchet.
This work was donate to Modern Museum of Mexiquense Cultural Center in México.
