Check out Capucine’s essay for an incredible example!!!
Thel Mina does a really great job of always linking what is happening in the language/devices/style/what the author is “doing” to her thematic argument (how the language choices enhance a point, develop a theme — she always links language to meaning).
General comments:
Make sure your thesis and your essay refer to the main concepts asked of you in the question (and reguarly link back to these concepts/ remind us of the the main goal + point of your argument)
Try to lengthen your essays a little more 🙂
