I like the rhymes, imagery, and a lot of the word choices, and I like how it builds to give the final line a lot of punch. I was a little bit thrown by the rhythm of the "To a furnace..." and "Obscuring every..." lines, I think I was expecting a pattern where they were shorter lines.
Thank you for your feedback, I appreciate your thoughts on the rhyming. In the first two stanzas I was trying to bury the final rhyme in the middle of the last two sentences, so "wheeled" was supposed to rhyme with "squealed". And in the third stanza I wanted final rhymes across the board but I think the change in rhythm in the last two lines sounded better in my head haha. :) Thanks for taking the time to give me your impressions!
