the face on this one looks like it's sliding to the right, I think if her left eye (our right) was brought down a bit, and her lips were angled on her left downard a bit, along with the chin, it'd be fine.
Yep...I have Leifeld syndrome sometimes. Not sure what causes it, but I draw eyes uneven on almost every face I do. That can cause a the rest of the face to get skewed too and I sometimes don't catch it until it's too late. Strange but true.
I do love the computer for that reason, it tends to show you the mistakes you don't catch when you're looking at it in person. have you thought about doing a rough/final, and then scanning it to see if you should finalize it? I try reversing the image too or seeing it upside down to check on accuracies. It's helped me out a LOT!
