For my English assignment I am talking about conflicting perspectives on Caesar's ambition in Julius Caesar (Shakespeare) and in two supplementary texts. One of the supplementary texts I have chosen is this sculpture of Caesar by Nicolas Castou: http://en.wikipedia.org/wiki/File:Julius_Caesar_Coustou_Louvre.png#filelinks
Could someone please enlighten me on how this sculpture portrays Caesar's ambition.

Thank You
