What do you think of my poem?its a bit allegorical...?

I really like the concept and the third and last stanzas are my favorite. This poem has a definite beat, and I think that in the 5th stanza the beat gets...interrupted? It was just a little hard to get back into it. I also like the format. It's kinda like that thing on Barney, "Green Gr Grows All Around". You know, where there's a tree, on the tree is a hole, in the hole is a bird, et cetera. You're poem has that feeling, like you're going deeper and deeper into something.
