Instead of painting it over with underpainting white, I thought I would try and use the previous painting for a kind of multi-layered background. Like I might do in my art journal. So I put a glaze of ochre yellow over the top.
While that was drying, I began another work, the same size. I also want to do a multi-layered background on this one, but this time with acrylic. I have put down yellow ochre and a layer of cobalt.
I have added more layers of oil to the first background. It is looking quite dark, and the figure isn't disappearing as I wanted.
On the acrylic background I have done a gesso resist print with a leaf, and then come back with more layers of colour.
Now I start to plan my composition.
I copied my drawing to a few different sizes to try them out on the background. Then I drew the figure onto the background and gessoed it. This is because I want to paint from a white ground.
I used the same compositional tool with the oil background. This time I tried four different sizes. The first one is too small.
I like this size. Would you have chosen the same one? There isn't really a wrong choice, it just depends on what you want to express.
