Hello, I'm a critic from ! I absolutely love the concept here! You crafted something that is short and sweet. Each stanza has some big imagery that clearly holds a lot of meaning, and that is a beautiful thing. I really love the heart stanza: it has a special life behind it that I really admire.
However, I would like to see you unify this piece a bit more. Two of three stanzas include "it's", it may seem minor, but the third should stick to that pattern unless you have some reason to break it. On the same note three of four stanzas finish off with "But..."; the last should be as well.
Overall, I love this piece, but I would like to see you take it further as well. I hope to see more of your work soon.
