Jo is a very talented singer, and I would highly recommend going to her Reverbnation site and listening to her singing the blues.
Here is a close-up of Bette's lovely curly hair. There as 8 layers in her hair and face.
I am finding that with adult faces I can use the black canvas as part of the shadows, building around that with the coloured cardstock.
I have been amazed at the colours and tones in a face - I just wish my camera could reflect them a little more accurately!
