This work draws on the Flemish many layered process that includes the dark warm ground, verdaccio/grisaille, piambura (dead layer) and houding (red/green warm/cool shaping).
Instead of the burnt umber I have chosen Alizarin crimson for the ground. I prefer a brighter palette than the old school Dutch/Flemish.
For the grisaille I'm trying Payne's Grey : - It just feels more contemporary (so far).
Next to let it dry and add the piambura.....
