Karin,
Below is the charcoal drawing in it's final stages just before the verdaccio started . Compare it to the verdaccio image above (painted) and you can really see a big difference. Yes, the charcoal was fixed with damar reworkable spray (ugh! Spray it outside!)and it is on a 14" x 18" canvas. I bought a gorgeous mahogany frame to compliment this painting. If I remember correctly, the verdaccio will be sprayed with Damar to accentuate the difference in the values. That's correct, Michael, isn't it?
There are varying amounts of chromium oxide green, mars black and titanium white in my mixes. Perhaps I should add more green next time, but for my first effort, I was more concerned with hitting the values correctly.
The painting is drying now and I will post again as the glazes go on. This is a project for the feast day of Our Lady of Guadalupe and the painting has to be delivered in two weeks. I hope they have proper ventilation!

People should really learn to give the artist more time.
Karin, Your copy of Ingres is beautiful and that thread is very helpful! Do you ever use this method for commissioned portraits? If so, do you charge more for this method which certainly takes a lot longer to complete?
