Focus on The Walking Man and explain the Praise.
The art historian Leo Steinberg said of The Walking Man’s pose: 
The stance is profoundly unclassical, especially in the digging-in conveyed by the pigeon-toed stride and the rotation of the upper torso. Unlike the balanced, self-possessed classical posture with both feet turned out, Rodin uses the kind of step that brings all power to bear on the moment’s work
