I really like this poem, because despite popular belief it can be difficult to master an acrostic. But you penned this well. The wording you used was great because the reader can picture this well. And you get to see the butterfly transform into something beautiful.
I do believe however this is a metaphor. I believe the butterfly could be someone you know or you, yourself. In life we all go through struggles and we sometimes grow into our own wings and colours so to speak. So metaphorically this could be some who has struggled but have grown into their wings. Wonderful and Beautiful write!
Firstly thank you so much for your lovely comments.
I don't feel it's about what is true of this piece. What is wonderful is how you feel from your reading perspective. So I love that readers have their own analogy of written poetry, which is sometimes the magic and beauty of creative writing. And I really enjoyed reading your take :)
