Films where I don’t recognize a single actor among the whole crew are almost always better than ones where I’ve seen such and such actor in other movies. Just more immersive. And even if they’re not the best actors I’d much prefer that over whatever the hell Chris Prat or Tom Cruise or Leo D are up to.
Just off the top of my head but I think you’re on the right path when it comes to sounding more eloquent. Poetry probably came from people messing around and playing with words to find what sounds interesting.
You’re already good to go on rhyming. So maybe just try for different rhyme schemes.
You might could also add other whatever-they’re -calleds like alliteration, consonance, metaphors, etc. Each of those are just a tools in the poet’s toolbox.
But what do I know!
