it turns out that the face i started below was jeanette's younger sister, charlotte! i had no idea!
i don't think she's changed too much... i added more white gouache and cream oil pastel to her skin, but mostly i worked on fine tuning her eyes, lips, and hair with watercolors, gouache, and oil pastels. her hair is mainly pale yellow oil pastel and gamboge gouache. i like to add oil pastels to hair without blending them in... i messed with her eyebrows quite a lot, seeing which color/s looked best. all the while i was messing with stuff i was trying to figure out what her left eye (as you're looking at her) needed. finally i realized that i needed to lighten the edges of it near the outside of her face, which i did with white gouache. then she popped alive.
if you click you can see the heavy white that i added to her forehead, nose, chin and neck - that's white casein paint. it's easier to get a layer of dense white with casein paint than with gouache. it's just a heavier paint.
the background is entirely covered with white casein, which i then painted on top of. on the right side you can see some faint flowers - i drew those in with a purple prismacolor pencil. a perfect example of the usefulness of colored pencils, i think...
i'll put a link to these posts in the sidebar so they're easy to access...
thank you for your positive responses and kind words!
