Newbie here! I don't know about verse terminology, but I hope this input from an inexperienced poet helps you gain a broader perspective of your work.
I think the general idea is that dragons are being misunderstood. People have a lot of misconceptions about these mythical creatures. You want to rectify that. I think this intention is a great foundation for the emotional core of the piece, like yeah dragons are bad, but no it's not that simple! Yes, they're dangerous, but why would they hurt you?
I suggest you really hone in on this.
Let's look at this awesome section:
They never tell you how it feels
To meet a dragon
to have your castle walls
Crumble
Feel the flames,
Hot breath on your neck
As the world you knew
Burns
When I read this, I feel intrigued. It's like a narrative scene. What is it really like to see a dragon up close? I'm imagining a personal encounter—it's intimate and terrifying. Like, tell me more. Show me the nuance of these fantastical beasts. Use punchy verbs, adjectives. I'm not saying that your work has to include fanciful words, but it could use a bit more specificity in its description.
Please tell me if I completely missed the mark here. I enjoyed reading this, and wish you the best on finishing it!
Edit: To expand on my interpretation—it seems that the dragons serve as a metaphor for some overarching idea, and you really want to convey that. There's a lingering conflict in this piece, that recurring "they say dragons are X, but I think they're Y" theme going on. I may be looking too much into it, but they seem to be opposing forces in a tug-of-war. I think the piece would benefit from focusing on this contrast with the two perspectives.
