I haven't been feeling well as you know and have had the hardest time with this piece. My advice don't use spray ink over acrylic on canvas. When I tried to add the face the reddish ink popped through. I added several layer of titanium white paint. I sprayed on a workable fixative, used a heat gun, then tried gesso and zinc white paint. Nothing made any difference. I finally added old book pages over it and started over.
I started with the sketch from last year as a reference photo. I don't try to make it exact but use the sketch as just a guide.
This is an underpainting using just titanium white and paynes grey. A technique I am trying from Gritty Jane's class in Life Book.
Here is step 2, where I add color, there will be many more steps to come. I had to stop for a bit. I am headed to the hospital for my pre-op appointment. I will update this later.
