Nice dude! Let's keep this thread alive.
Ok, so your poem... first off, as a personal fan of FFVII, KICK. ASS. CHOICE. on the topic.

Now, onto the criticism...
I like the flow of the poem. It's consistent, and it's got a nice pace to it. There are a few spots here and there where the pace gets a little disrupted... For example:
Reign of hate and greed and fire
Hades looms above
Sephiroth the question asked
Is "do you have no love?"
The answer back is not for us
The mortals of the Earth
Who live in fear and pain and grief
From Birth until the dirt
both bolded lines are a bit too long... at least, that's what I thought. It happens again a few times in the poem... however, the solution is simple: don't over-use words like "and."
Instead of
The angel has no sympathy
And he won't hear your anguished cries
try
The angel has no sympathy,
And won't hear your anguished cries ---> (or remove the and leave he)
Also, some lines make little to no sense at all...(or, the don't really "belong" where they are... at least, that's what I thought) like these:
Upon your wings alight
Yet you demon I know you well
Sephiroth the question asked
Is "do you have no love?"
The answer back is not for us
Leader with an iron fist
From life and light To darkened night
On this last one... it's a bit long. So, my suggestion is to add a line break before "To" and/or change "darkened night" to something more parallel to "life and light" (death and night or something...)
On a positive note... You payed the proper respect to good ol' Sephi. You managed to capture the feeling you get when he stares at you... so cold, ruthless... so perfect. I absolutely LOVED the last two stanzas, I think it was a great way to end the poem.
So, the basic advice is: don't over use words like "and" and try to re-word some of your sentences... the content is good, but the choicew/order of words makes it confusing at times. I like your style, you depict the "feel" of a character rather than the feelings he produces and/or the character himself. Nicely done. I hope to see more soon.
