smoke signs

[Keith]

smoke signs in altitude

clouds left my mouth,
leaving me
with less breath left
to give reply.
this one goes out
into the sky,
grows furtive wings
to be unshaped
and then
to be erased in wind.

as always (though in misc) heavy crit on form, grammar and whatever would be welcomed, as well as (and that´s why it´s in misc) interpretation/ short feedback on what it says.. though i guess there´s not so much to interpret here

Reads like someone blowing smoke rings and watching them drift appart, if its a meta, then could be about a relationship breaking up, the second use of left is a bit bumpy could be
clouds leave my mouth
with less breath left
to give reply

Grammer...Capital letter after a full stop ?
Form...Mouth, out...less, left....reply, sky....wings, wind I like them all and all works well for me.
Best Keith
