I love the tempo in this poem! However, the punctuation is a little inconsistant. In all but the last two verse paragraphs, each and every line ends in a period regardless of the necessity of said period, while the last two verse paragraphs are more grammatically correct. You could choose to go either way; if you want it to sound especially clipped and chopped, go with the periods. I don't think you need them, though; the meter gives that sense by itself and you can stand to remove some of the periods.
Also, I'm having a bit of trouble with the word "ultimate" in stanza three. It doesn't seem to fit, and it doesn't give a clear image. Perhaps a different word?
