Great imagery--I know you've heard that already--but that's a good thing. I love the last stanza. This isn't usually the kind of poem that would intrigue me, but I think this is very cute. Simplicity can be good, and you proved that without using juvenile words. Great job!
"It is in truth not for glory, nor riches, nor honours that we are fighting, but for freedom -- for that alone, which no honest man gives up but with life itself." -- Declaration of Arbroath
