Your image conveys to me that loving moments are expressed in many different ways, whether it be the loving embrace of the human couple or the joyful interaction expressed between the sculpted mother and child.
The people of bronze seem more sure of their relationship than those of flesh and blood do here. The human couple are probably responding to your presence as a photographer, and give you an awkward "caught in the act" expression. In contrast, the sculptor's concept is idealized. You give us a story here that is based on the juxtaposition of idealization and reality, Rose.
