Okayy so this analysis is really good, especially for a year 10 level. The main thing I have to suggest is to add some contextual statements, such as what exactly these "societal ideas and issues" stem from - was the poet living in a time of war and conflict, did they experience personal losses, and so on? This sort of information adds depth to your understanding of the purpose of the texts. Context will be crucial in senior English essays, when you engage with each of your texts and their authors' backgrounds a bit more. Also, I'm being quite picky here, but I'm pretty sure alliteration only works when the sounds are at the beginning of words or stressed syllables, so you might want to fix up that analysis statement - you can say consonance/the use of plosives (which includes the "B" sound).
