How to tighten and open at the same time--tough!
Forget all conclusions.
Treat any prompt as an excuse for exploration. Come on, this is an opportunity.
If voices have layers, what's the next one deeper?
We're familiar (we English-users) with fine-tuning. Suppose your poems are tuned, where's the fine part?
Why not make your title happen, the first kick at your reader. (But is that what you want to do to your reader?)
Yes, you have an opportunity to explore, what you, and only you, can write.
Don't write poems to please me.
Dare your own voice to way what it really wants to.
Don't forget that an ego--that-which-you-think-you-are--tends to be at work in the word "I", but the voice doesn't have to speak that way.
