Okay folks, here's the next installment. All old masters materials again. From a photo ref by Steve McCurry.
Here is the walnut ink drawing on gesso panel:
Then glazing over the robe with green earth. Right away I ran into problems, as there was too much brown for the green earth to cover well. But I bravely continued, using the green earth as a couch to paint into the lights with a homemade green bice (basic copper carbonate) pigment and a bit of lead white:
The orange bits are minium (red lead). Then, after drying, glazed over the green with Antwerp blue (the only post-Renaissance material here), and natural carmine over the red lead. Finally skin tones and background, all with natural earths, bone black and lead white:
... except that I glazed over the lips and cheeks with madder. Lovely stuff. Who cares if it will fade eventually? So will the model... and myself, and everyone who looks at this painting. Here's a closeup:
This one was more complex and I didn't plan some of the colors quite right. Working glaze over glaze, things sometimes don't turn out as planned. Next time I'll have a better idea how to tackle something like this.
Got at least one more in mind (probably two), which will include egg tempera between the ink and oil layers. Stay tuned, and thanks for looking!
