I cannot recommend anything specifically, but it should be pretty clear by now that all those skills come from reading more. The people good at analyzing literature are those people who grew up reading all the time and really understand that stories are often parables for much of human behavior. Consequently, I’ve found that being “aware” in a sense, or understanding motive and psychology, human behavior once again, can lead you to, in a way, backwards analyze literature. Start with the meaning and look for the clues so to speak. As writing is often steeped in personal meaning, it should follow suit that understanding humanity, emotions, logic and everything and otherwise, should be key.
