Garth,
After looking at your refs several times I feel that the most pleasing one is the first one. The reasons are: her slightly sidewards turn and the extra height at the button makes her appear slimmer and taller and at the same time adds more energy to the diagonals.
Her expression is pleasing, but not too much, thinking about your other ( male ) judges that will hang beside her, I think that the #1 ref is fine.
About the hands: The #1 is fine too because it is clear and harmonize with the figure, while the #4 is more puzzling. But you could use it for PR if you put your signature down into the lower left corner
