I’d recommend writing on his ironic affection for his local surroundings, the religious atmosphere of his poetry, the repeated images of isolation in his poetry and the childish viewpoint. Think about these paragraph topics, or others you are doing and structure as follows:
1) introduce the paragraph topic
2) say how it is an interesting element of his poetry
3) provide examples, quotes etc
