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!
Is this any different than EPA rated MPG listed on vehicles? Obviously their quoted range is an absolute best case scenario. Still fun to meme on the cyber truck though.
