Finally finished!

Well, here it is.  The harpy now has a base to sit on, which is a major improvement.  The shape and weight distribution of the head mean that it can't stand up on its own, and needs a base to support it.

Another advantage of mounting the harpy on a base is that it prevents the crest of feathers at the back of the sculpture's head from getting squashed.  The crest looks much better displayed this way.

Originally I was going to put a quote from Aeschylus' Eumenides around the base, but sometimes less is more and I decided it looks better as it is.
