Kurt, you can see the photo reference if you google image her name
it was the first photo for me, might or might not be different for you

even in the close up it still looks a little off, it might be the shadow, but i don't think so

sorry to graffiti on awesome work but i took a screen shot and shifted the eye over and raised her eye lid up a bit at the bottom by cloning...
yeah it's a little crude but i thought it looked slightly better, although it's not in the same position as the reference

it's hard to say what it is that's throwing it off but it might be her right part of her left eye is too open?

but then... i just pop her picture ontop of yours (and it matches up perfectly...) and now it's too hard for me to tell that there's something wrong with it......

the lower eyelid of her right eye (i don't know body parts) could be raised up a bit more
