The message this poem conveyed just hit back home for me when I made it to the bottom. The rhyming flow of this poem is amazing and the way it ended has me craving more poetry or literature from you. I cannot suggest any where to improve since all artists succeed in getting their message across no matter the length or diversity of their work. And you are a testament to this with this awesome poem you just wrote.
I see no spelling errors, and there's no room for me to bit nit picky about anything since it's just so simple yet so brilliant. I love it, keep up the great work.
