I really like how you ask even the littlest questions about life. Not the usual, "why are we here?" or "what is the meaning of life, the universe, and everything?" kind of questions; but why our names, eyes, race, and even why-not's like:
"Why wasn't I born
From a rich, noble king?"
I did notice a semi subtle rhyme scheme throughout the poem, it really gave it a good drive to the piece. Now of course if there's usually a rhyme scheme there's usually some sort of rhythm; there is one, but again it's really subtle. Having four lines per stanza is pretty standard to me, but it does give the poem some basic structure.
The last five stanzas I love because they aren't applied to one, specific belief. It's ambiguous enough to make the reader think and, by the off chance of this occurring, preventing anyone from getting offended.
Overall, I really love this. I love the concepts and ideas presented and the structure's good despite it's simplicity.
