I think Diana would have been better depicted in marble as it has a more luminous quality than bronze. I think her face looks hard, and the arms, heads, proportions and poses of the children look awkward. I can’t stand the outfit of hers they chose to use. Of all her outfits why that one! The belt is far too in your face.
Also Diana SMILED when she was around children, where is her beautiful smile that could light your heart in and instant?
