I did a couple of different takes of this shot, some open, some stopped down. The stopped down ones bring Virginia King's sculpture into sharp relief, but in the end I thought that the shallower depth of field with this one (f/5.6) provided a combination of adequate detail plus the "abstraction" that king is looking for in her sculptures.

Addendum: My personal opinion is that Facebook is a sociopathic organisation that steals other peoples' intellectual property (including the images in this gallery) despite being explicitly denied permission to do so.
