Hey, nice to get out here and start posting with u, buddy. Well, u said you wanted an honest critique, so I'll try and give you one. But you have to promise to give me some insight too. Deal? Cool.
This poem definitely sounds like something you'd write. It's ripe with wierd metaphors that people might not get at first. That's not because we're stupid, but it's more because we're not as obsessed as you are with writing every single thing in this world in terms of metaphor . What you've done, personifying the era, is a good idea, but it can be taken a little too far.
You sort of contradict yourself in a way. First the new era is something almost reared by the previous one. But then, in the second stanza, it goes in two completely different directions. The old era is both a teacher to the new one(I mean, why else would it "call" the new one an apprentice) and a force conquered by it. It's an interesting paradox and I think you could expand on it a little more.
The ending is a little weak. It sounds too cliche. You should bolster it a little more. Hey, you could even throw in a little about just what you're talking about in the previous two stanzas! If "this is the way we all must go" why don't you talk about that way? Is it a military way, or is it a pedagogical one? Or is it both?
Sorry if I was a little harsh on you there, man. It's a good poem!
