Sarika, You pose an interesting question.  Emotions and their affect on rhetoric is a good topic.  Your research is sound.  I would only suggest that you connect your introduction to the section about the speech by Mark Anthony.  It was a little hard to follow your thought process.  You give good examples of the use of emotion.  For example; facial expressions, equivocation, and parrallelism.  If you tie it together with a few phrases you’ll be on your way.  I like your topic.
