I started with an old canvas that I painted over with the red ground, as seen below. I used cadmium red, which is so so strong. I thinned it out quite a bit, even so most of the original painting was gone.
The next step was to do a loose drawing, as seen below. Once I did that, I used my palette knife to lay in a lot of paint, focusing on values. I thought I had a photo of that but I guess I didn't stop. I really struggled with my final photo because of the lighting, I need to replace some of my internal lighting.
