Below the Flesh

[UnicornRainbowCake]

Below the skin: Flesh.
Below the flesh: What I am.
But… what am I? This stanza for me doesn't state anything that we don't know. I'd cut it out, it doesn't add much

Bones, muscles, blood, vessels;
Veins, joints, chemicals, cells.
Words, thoughts, dreams and hopes.

Four micrograms of dreams,
Still and overdose, it seems.
Gotta keep on dreaming, by any means,
For in my dreams, just for you, my love beams. The rhymes you have started here sound like Yoda talking because you're trying to force a rhyme in. I'd cut out the rhyme altogether, you didn't use it earlier on, no reason to start now

And that is what I am too:
Dreams of love, about me and you.
Sometimes they make me blue.
Blues is what I am, that’s true. Same as previous stanza

Fear crawling in my depths,
Triggering the sorrow… should I pay my debts?
My ancient fathers gave me a new tomorrow.
My identity conformed, too, by my regrets.

And don’t mess with my hopes,
Can’t you see they’ve torn off their ropes?
Still, in my hopes, my faith it chokes.
Revolting guts, what it provokes. Same rhyming problem

Impatiently patient, I come from the ancients.
Like them too, as the smoke of the incense,
The day will come when my breathing ceases;
When I, as a “whole”, will be gone and I’m left just to pieces,
I will stop being a physical presence
…And I will fade away, what remains will be my essence.

I haven't gone fully in to depth because it's in novice, but personally, I'd just get rid of the rhymes. Rhyming doesn't always make a poem any better, and in a lot of poems, makes it worse. I don't in any way think this poem is bad - I love your imagery, and the tone. Just try revising it without so much emphasis on rhyming.
