Can't get back of hair to move with head and eye gaze help

I found out why the puppet's eyes didn't move.
However, it is difficult to explain in English.

I uploaded the sample puppet to Dropbox again.

The pupil seems to be too wide.
If you try to divide the appearance of the pupil layer, a square frame will be displayed.
It seems that this square area is recognized as a pupil.

By deleting this square frame, the pupil moved up, down, left and right.

I converted Japanese to English with translation software.
 
1) The head layer does not have a crown mark.
2) Hit the fixing pin on the foot of the body layer.
3) Put the back hair layer in the body layer.
4) Put a crown mark on the back hair layer.
 
I uploaded the modified puppet to Dropbox.

Although it is in Japanese, the commentary video has been uploaded.

Sorry.

I tried various things about the movement of the puppet's eyes, but it didn't work.


Thank you
