Can somebody please help me with this Romeo and Juliet essay?

I’m supposed to write a six hundred word text based essay answer to this question
“Explore in detail how Shakespeare presents the characters of Lord Capulet, Romeo and Tybalt in lines 43–91 of Act 1, Scene 5. Support your points and arguments with evidence given from the text.”
I don’t feel there is too much I can write. I’m supposed to explore the characters in relation to the literary devices, techniques, methods and tools employed by Shakespeare, the text and themes present, and the effects of the devices and other things I listed above on the audience/reader. And of course the character analysis itself. Can anyone please give me some pointers on how to go about this and help me identify things to write?
