I am tickled to death with this one. It's a copy of one of Picasso's many paintings of Sylvette David. In the 1950's, she worked in a pottery shop where Picasso kept a little studio at the time, firing his own pottery. She had beautiful blonde hair and often swept it up like this, and he noticed it and made as many as 40 different portraits of her. She became known as "the girl with the ponytail" and her hair was imitated by stars at the time, like Brigitte Bardot. She was very shy, avoided the public scrutiny as best one can when made a star of sorts by being a muse to Picasso. She is firm when saying he was always respectful of her.
Anyway - I came across this one and was struck by the grayscale style. What?!

Had to try it. I used a grid for this one, because the proportions are unique and I didn't think I could eyeball them.
And because I'm so tickled with how it turned out, I will torture you visually with my WIP photos.
Here is my sketch over the grid pattern I made (I don't do those tiny grids). Notice how I got the eye direction wrong; I realized it later and corrected her gaze.
I did the background first, and worked on the face, correcting the direction of the eyes. I erased some of the grid lines in the head, but they're still visible in the sketch.
Got to working on the hair, scumbled in some dark gray in the neck there, shadowing and such. Then I got more absorbed and didn't take any more pics. Lucky you.
This one was so.much.FUN. It was weird. I broke out every shade of gray I own. It's fun - so many grays move towards blue, some stay in the typical middle-gray tone. Even whites are different between manufacturers. I knew all this, but never had a palette where I could
only work with them.
I learned a lot doing this one. I hated coming to an end. I will miss this girl. *sniffle*
(Note: Sylvette David is still alive, and goes by her married name of Lydia Corbett now. Picasso gave her several of the paintings and sketches. She studied art and became a painter in her own right. Yay!)
