Similarities/Differences.. HELP PLZ

Hi All.. I am writing a term paper for english due this thursday and I am curious of the similarities and differences between a TALE OF TWO CITIES and GREAT EXPECTATIONS to incorporate into the paper. I already have some ideas, but if you could send me yours it would be greatly appreciated. Thank you and best regards!

One similiarity that comes to mind is examining Magwich's character and Carton's - the fact that a person is not always as he seems - and that people do reform - I think they're very similar.
