I assume you're not around user, but I thought I'd wait until the new thread to post. My bad on not replying right away, I think I went to sleep just a few minutes before you posted.
Your poem does a good job with the prompt given. I didn't write for that one, but other than "serpent" it seems like most poems would naturally end up more light and bouncy.
But, do keep in mind, though I had it easy myself, others may find it a hard time to read a poem that rhymes and enjoy it if each line is a different length than the last with no rhythm to it.
Surprisingly, even though you didn't use any syllable rhythm with your rhyming, each line felt like it rolled pretty well. I read your poem twice, once in my head and once out loud, and each time I think I had the same "tempo" in mind.
However, with that, in the second read I found that I had some trouble with the first stanza being three lines (as well as the last stanza, but not as much) vs the rest of the stanzas having four. Again, you didn't use a syllable-rhyming scheme, but the stanza's length felt out of place.
Honestly, in terms of writing, I can't find anything that completely turns me away. I especially like the fourth stanza "mine own wrath," it just pushes that stoic feeling.
There are a few word choices and lines which I would change personally, but I'm not sure if they're worthy of change critically. For instance, "a demon of destruction," though it rhymes and makes sense to the rest of the poem, I just don't like the word destruction very much. It's not fair to call that out as bad word choice though, just my preference.
Also, this might just be my interpretation, but I like the doubled inclusion of "the Miracle," I assume that's religion but since you're worldbuilding a little bit it could also be some other magic.
I tried to bulk up this analysis but I might have just rambled at some points. Anyways, hope you see it. Good poem.
