Really nice. It's actually very simple, but it's written in a way that allows the great appreciation within to show.

The thing that makes me hesitate to call it "great" is that it sounds familiar, as though I've heard it before. The rhymes just somehow seem borrowed.

But like I said, the appreciation shows, and that's what it looks like you intended. Good work!

the rhythm works really well, and the rhyme isn't too forced. good work! :D
