Here's a step by step of a painting I did today. I've already posted it for sale on Etsy for $130. Please visit my page:
Here's the underdrawing. I did with a 30% grey marker. Next, I coated the canvas with burnt umber.
Next I wiped out the light areas with a q-tip and a rag.Next I rested the darks with more burnt umber mixed with a touch of lamp black.
The rest of the painting was done with a palette of cadmium yellow, cadmium orange, and white.
