Hi! I'm not a teacher.
As a non-native speaker, your analysis about the poem is pretty good in my view.
- Please double check your tenses in your article again, especially, the words I hightlighted in red. You alternated present tense and past tense now and then.
- I am afraid you might not really understand the sentiment of the poet. I'd suggest you read the poem time and again until you really understand each word, and each verse, eg. Sophocles, the poet meant to. Of course, beauty is in the eye of beholder. There's no standard key to a poem. You can interpret it in your own way.
- Here's an analysis I searched from Wikipedia as below URL link directs. Please remember that it just helps you to understand the poem better, copy other people's work completely or any part of it under another name that will be considered as plagiarism. You do should hold your own opinion.
- You can put it up again for teachers' suggestions after your revision.
