John,
I suspected that you've bought the Griffing book!
I had to refrain myself NOT buying it because it would be too easy to draw my inspiration from/copy it. I know, I'm a masochist at times!
What do you mean by 'doing the headdress separately'? As far as I can remember, the hair/ribbons was moulded on the head with a separate bunch of feathers, if that answers your question.
