Hey everyone

This is a piece I've been working on for some time now, and I just can't get some stuff right...
My main issue is with the anatomy of the face. I've tried over and over to fix it but it doesn't seem right. I know some other things are wrong (like the hands being too big or badly shaped in some areas), but at least I know I can fix those.
Another problem is with the shape of the lower part of the dress. I think it could have a more interesting shape, but again, nothing I do makes it look any better.
I'm also planning to add a second lightsource from below, since the painting itself feels kind of dull as it is.
Any comments or help are greatly appreciated

Thanks for your time!
