Some of the rhyming seemed lazy like "High I be", this seemed to not flow well and screwed with the rhythm of the poem. I did however like the angst and the dark tone. I am a cynic, so in reading things that are dark I find amusement and this definitely amused me, despite the lazy rhyming.
I loved the rhyming and the rhythm was really catchy and it was easy to follow unlike so poetry. Your poetry was straight forward, it was about the color green. Your poem doesn't contain abstract words that only someone who studies dictionaries word for word would understand, it is simple and beautiful.
