When to stop, when to press on, what to do… the ever present questions. Yesterday I applied a rough layer of grey (mixed with ochre).Then I worked with asphaltum, burnt terra di siena, white, etc. No added oil, just dry, thin layers.Normally a single brush stroke can make a difference, but since the head is about one meter big, the reality is a bit different. I should let the work rest now, but it is hard, it is like a riddle, a mystery that needs a solution and it becomes somewhat obsessive.Below a close up of the face.
