I was unsatisfied with the mouth, so I changed it to an open mouth which gave her a more engaging look, as there was plenty of room on the lower face. 

This is an example of how you can critique your own work and make improvements.  If I had botched it up, I would just have had to make another head, so it wasn't a biggie.  However, I think I am happier with this now.

Of course then I had to add all the other bits to finish her off and make her live up to her name, which is "Practical Pindora!"  She is to be my new pattern, which I am in the process of finishing off as we speak!  What do you think?
