It is improved now – but still not metrically correct…at least it has 8 lines!
Beneath an almond-marbled sky,
headstones standing to attention,
and side by side veterans sigh
their pride at every comrades mention –
once close friends from days gone by,
tree limbs stretch in supplication.
The skies release a weep of rain –
an all enveloping cloak of pain.

“headstones standing to attention” I really like this!
Thank you – they stand at attention for eternity, don’t you think?
