You made the center alignment work for you congrats since not a lot of people take advantage of that nifty tool that we have.
The first stanza rhymed all the way down since I read it out loud and it sounded really cute especially the ending since it made me smile as again I love dark love and the last part hinted at it.
Second stanza doesn't rhyme in the beginning but then it does and it's sad since many people are ambitious but not all get to go to the top and that's what humanity is.
Overall I liked the flow and the rhyme of this piece most of all.
