This is a new process for me, I think brought on by doing more charcoal . The sketch is done on a white canvas ,then I used a workable fixative (it dries quickly). This permited me to paint directly over the sketch. The paint I used is alizaron crimson and veridian green mixed gives this pretty lilac color. When this under painting is completed I'll decided what other colors I'll add. I'm really enjoying this ,I really needed a change .... good for the soul.
