Terri,
Glad to see you're trying oils - I'll be excited to see how this one turns out, since I'm a big fan of your acrylics.
Keep us posted on your progress, and how you're liking the oils vs. acrylic.
I like what you've got so far. The one thing that popped out at me was that the shadows in the mouth could use some lightening, but you already mentioned that so I guess I didn't even need to!
