Update. I *think* the head normals moved up along the z when I copied it. So I moved it down by eye and now things look better.

I do however have stretching of the eye sockets from the side – is this correct?

I do still have this artefact from the asymmetry tho which annoys me
[ack! can’t upload this image as only have the ‘image URL’ option]
