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
The bird that would soar above the level plain of tradition and prejudice must have strong wings. It is a sad spectacle to see the weaklings bruised, exhausted, fluttering back to earth. — Kate Chopin, The Awakening
