Hmmm. This is a wonderful poem. The flow was nice and the imagery was nice. However, a revision would have been nice. There are two parts that seem out of place to me.
"Falling down like snow." (You can take the down out of that, it'f make it flow easieer.)
"It lies there on the floor." (Because you're rhyming, you had to force a word here. The world is on the floor? That doesnt even sound appealing in a poem. )
