Topic: May I ask what is considered a good literary character essay introduction and conclusion?Hi guys, hope you all can help me with my question....

Just to add a few ideas--

Perhaps you may wish to include in your introduction a passage from the play that exemplifies the characteristics of the character that you will analyse.  For instance, if one writes about either Brutus or Cassius, the famous line of Brutus,

No, Cassius; for the eye sees not itself/But by reflection, by some other things (I,ii,52-53)

acts as a fulcrum to launch the analysis of the too idealistic Brutus whose envious friend Cassius acts as his

glass/Will modestly discover to yourself/That of yourself which you yet know not of. (I,ii,68-70)

Or, if you analyse Cassius, you may wish to use his own words which prove  true:

Men at some time are masters of their fates:/The fault, dear Brutus,is not in our stars,/But in ourselves, that we are underlings. (I,ii,139-141)

Remember that in the final act, Cassius himself becomes superstitious and, therefore, contradicts himself--interestingly.  This contradiction certainly reveals much about Cassius. 

These quotes or other cogent lines will, as akannan suggests, initiate the analysis of the character that will "open the reader to a critical thought process."  After all, this is your objective in a character analysis essay:  to convince through logical reasons the reader of your thesis.  Then, in order to conclude with a "clincher," you can certainly turn again to a relevant quote.
