Be careful with complicated terminology though, you don't get brownie points for making your essay hard to read.
Your final aim is to write an essay which contains:
1) A good argument, based on good ideas with good evidence
3) Professional and academic language
So I think you should be aiming for basically around about the same language level as an opinion article in The Age. Don't try to use too many complicated words or else your essay will sound like this:
The use of complicated wording as an overall literary technique needs to encompass graphic and individual comprehension to allow the reader to become acquainted with the unique terminological aspects employed by the author whilst not detracting from the application of the specific innuendos influencing the particular methods involved which reflect the tone of the major works in question, thereby altering the quality of the outcome.
Try reading it, all at once, I bet at the end of it, you'll be forced to read it again, because it's just too complex - remember - easy on the adjectives and easy on the adverbs. What you want is one nice adjective to describe what you're getting at instead of five mediocre ones.
