I like the theme, and good use of free verse with and ABAB rhyme scheme for the first four stanzas. there seem so be a few enjambments as well.
The poem seems to follow another style quite suddenly at stanza 5-7. And they also felt a bit unnatural and could use more personal touch or refinement. Stylistically, I find "so" or therefore in the last stanza or at the end of poems unnecessary. The poem could be enhanced by allowing the poem to speak for itself. without the therefore/so at the end. It can even feel as if the speaker ran out of time or space to continue the theme of the poem.
I hope my comments do not come off as too harsh and can inspire you in your future writing. Keep in mind these are my opinions only and other readers and writers may disagree.
Thanks for sharing your wonderful art, and keep writing! 😃
