First of all, I prepare the background with primary yellow and black (mixing an excellent olive green), some bladder green and bright green. It is advisable to create a backdrop with blurred but well-defined spots, in order to make the base work less flat.
Once the background is dry, use a white pencil to trace the subject previously studied on the canvas. Using green as a base color may seem risky, but it will allow me to tone down and in some areas exploit it in transparency. Give the fox greater volume and realism.
Before moving on to painting the cloak of the animal with diluted black, I quickly define the focal points of the composition, that is the eyes and nose of the fox, which in the magma of the successive brushstrokes may risk to be lost.
My palette is composed of: medium cadmium yellow, red ocher, amber light (a yellow napoli is good too), burnt shade earth, natural sienna earth, bright red, light gray, white of titanium and black. Mixing yellow, ocher, red and sienna
