Meanwhile, Axis has no difficulty posing his head at all. He can look up or down with ease. So I decided to do a few comparison photos to check the difference between their heads.
Pretty profiles. :)
Highlighted for emphasis.
I can't make Alice's head move up at all. Axis can because the base of his head is 'straight' and no resin part blocks his head movement.
Highlighted here is the 'blockage' on Alice's head. The bend on the back prevents her from looking up.
I forgot to take a photo of them looking down, but Axis can because he has a bit of space towards the front of the base of his head. Alice does not have a space in that area.
Having kips or sueding the head should probably help with the posing. Alice once has a kip in that area (it accidentally ripped so I had to remove it) and as far as I can remember, I can somehow make her look up and down a little.
