Is there some special technique for the sandpaper exercise?  y actions don't seem to produce any change.

You have to place the sandpaper over the cracks on the doll's face.
If the position is correct, the sandpaper will be slightly highlighted.
Left and the crack will be erased.
Repeat the operation until there's no crack left.
I hope it helps!
