Pretty racy character for kids, eh?

 I would change the camera rotation rather than change the character / prop rotation. In theory this would keep your shadow parameters consistent. BUT when the camera is behind the character, the illumination would be pretty dark depending or the direction and type of lights you're using, so I'd probably use IBL or (an array of point lights spaced evenly throughout the scene) for fill lighting, no shadow casting or AO, no image - just constant color, set to whatever your fill lights currently are
