Reddit mentions: The best poetry literary criticism books

No specific feedback on that poem (I honestly don't think it would help you at this point, if you're just starting out), just some general advice:

It takes a long time and a lot of work to become a good poet. Just try to write regularly and read poetry regularly - every day, or at least 4-5 days a week, if you can. Most of what you write will be pretty bad, and some of what you read you won't fully understand. But that's okay. You'll improve as you write your first few (dozen, hundred) pieces.
