I wonder how long it took you to wrote this.. I'd imagine it took quite a while. I really love the multisyllabic/internal rhymes, and the syntax you used to stress certain words or phrases: ex:
'Who lives a life -mere shell of existence-.'
'Upon shower of guilt and woe unbeknownst is[am?] I'

One thing that I did sort of notice is that maybe you got carried away with the rhymes and didn't pay due attention to content / rhyme / imagery.. Also, the different structures of the lines could have thrown me off in being able to pay attention to each of the qualities of this poem; it's certainly a poem you'd wanna read out loud. In the same vein, I think some of the rhymes were a bit forced;

Into the darkness for fear of perceival
Of the vicissitudes and reasonless relieval

and

I feel alive again and the sky
Seems to open it's hope to myself and I

some of the imagery was a bit out of touch; maybe too abstract to swallow.

Because now the glass of sun is set
At fingertip for occasional sips adept

Though the entire piece used beautiful language and so many different techniques, I can't help but wonder if maybe trimming this would increase its effectiveness. Dont get me wrong in any of this; I could never write such a good poem as this. And, again, I'm definitely a fan of big words as well, but using too many can and will cloud the connection held between reader and poem/poet.. just some stuff to think about.. cutting my rambling short.. pZ out !
