Great review as per usual Michael, I have been enjoying you honest appraisals for years now and love your work!
My take here...
Bad production Quality Control on Darla, bad, bad, bad and in need of a vigorous spanking or caning or whatever they do there.
The forehead and chin are not Andy's, I think they believed they were producing one of those foreheads from "This Island Earth"
As far as the controversial Willow, bad paint apps, bad bad bad, in need of even more spanking @ SSC QC. I purchased a repaint Willow, same exact sculpt and she looks so much better, almost cute even, although her eyes were painted a bit too large, it still shows how much better she can look with better paint apps (not like some 45 yr old woman from Bensonhurst).
Here you can see a "correct" repaint Willow.
So, everyone please take it easy on my boy Andy, he is one of the best if not THE best sculptor out there!
