Straight out of your head ... Is what some people work on for days.
I have this anthology text book and one cool bonus is that in the back are " unfinished works"
For whatever reason ( death ... Abandonment ..) the poet didn't finish them and in addition to that there is " works in progress " lets you into the poets thought process.
But yeah straight off the top of your head very very good.
You said it needs work , can I venture to guess changing the numbers of the lines in the stanzas. 7,9,6 ... Give them 8 like a sonnet maybe?
Let's try a limerick see if I can remember lol
