Sestinas aren't easy, are they? Choosing the right six words can be tricky. I’m not quite sure where you were going with this poem. You didn’t give it a very telling title so I feel like perhaps you weren’t sure where you were going with this either. I'm getting a lot of themes all at once: change and turmoil, lunacy, pain, love, peace – they’re all good themes, but they don’t really put an image in my head they way some of your other lines do, like this one:
Just one more sunset and the moon will rise
It’s hopeful and at the same time ominous. I really like this line. I'd like to have seen more lines like it. A line like that speaks to me a lot more than one like this:
To fight for peace is just lunacy
You followed the structure well (had one or two typos, but who really cares), but I found it strange you made every line a separate sentence. That’s not a criticism, just an observation. Any particular reason? If there was one thing I didn’t like it was that the poem seemed too rhetorical, that is, too many words without enough imagery. Too much tell and not enough show.
