research paper sonnet 18-- guide for a paper?

This is probably Shakespeare's most famous Sonnet. It's the really romantic one. Yes, the theme is kind of narrow for a lengthy paper. I suppose there is something behind the natural elements that he chooses. There are a summer's day, wind, clouds, spring (" bud's of May"). Nature becomes a personification of her or his (We aren’t too sure which "team" Shakespeare played for) beauty rather than the other way around. So, if you wish to spend some time overanalyzing nature's elements you might have something or you might just pick another one.
