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.
