Enjoyed, fitting title and especially liked the line-
now the days grow cool
and they grow short
you've so graciously
given the birds
the last of yourselves
one small nit in S1, should "heads" be "head" singular as L1 refers to you. I am uncertain as you could mean you all, as all in the graveyard?
Thanks @beginningtoend! I was actually imagining a group of sunflowers when I wrote this but the image used doesn't really jive with my original vision.
