A conclusion should
include a comment about the two writer's. And a comparative comment
about the texts you've just written about. I don't expect you will write
anything new in this part of the conclusion.
Secondly
you could make an observation about the poets or poems you have written
about. It may not be strictly relevant to your essay but you may
consider it an interesting and thoughtful observation and this is worth
sharing.
Don't
worry about a conclusion at this point. Two or three short paragraphs
giving an overview of the topics and observations you've made about the
topics you've covered will be fine.
