How can I write a well structured analytical essay on a poem?

Example Poem: "Daffodils", William Wordsworth
When writing an essay, we begin by looking at our text and analysing it we try to signpost all the interesting devices which the poet has used to make the poem more than just words on a page: symbolism; metaphor; simile; repetition; rhym;e rhythm; personification.
Once we have signposted all of the things we can notice, we can start to group together our points into paragraphs. For example, we can split our analysis of this poem into three elements: the personification of the daffodils, their comparison with the rest of nature, and the poet's own experience.
Once we have done this, we know what we are about to write, so we outline the main points we are going to make in our introduction. To start the first paragraph, we write a topic sentence. For example, if we are writing our first paragraph on the personification of the daffodils, we need to signpost this: "Wordsworth vividly depicts the beauty of nature by frequently personifying the daffodils". We then go on to give examples of this and explain why these textual examples add to the feeling of the beauty of nature that the poem gives us:
"for example, when he states that they are "dancing in the breeze", he uses a verb which would normally apply to people moving in a synchronised and beautiful manner. Therefore, personifying the daffodils as such emphasises their beauty, a it suggests that they are not moving randomly, but in an organised, elegant way. This is further emphasised at the end of the fourth stanza when the speaker states that they are: "tossing their heads in sprightly dance".
We repeat this method for the following two paragraphs, and then write our conclusion.
