Thanks for the comments.

Yeah, I think you are right. Looking at the reference 'in profile' picture again a do notice her head is turned very slightly towards the camera.
It is hard to find good reference pictures from the side of the head.

The bottom eyelid crease might have to come slightly forwards, but I do like the rounded feel of it.

It's a work in progress and it is my first head morph done outside of Poser anyway. I have plenty of experience with creating dynamic clothes in Silo, but morphing a character, especially across seams is a bit of a challenge for me.
