This is after I painted upside down to get proportions right. It helps the brain see what is rather than see what it thinks it sees.
I think I can finish the painting upside down. I hope to let it dry enough to be able to show contrast. If the paint is wet, the colors blend together.
I need a translucent fleshtone. Mine is solid and is a dud to work with.
To get skin color, use dark red and green first. Let it dry. Then, add layers of white, brown, peach, and orange. Let those dry. Use more and more oil with each layer.
