At Night

[Erthona]

I stare throughout the window, ("I stare out the window", throughout makes no sense)
without a word nor a move, ("without a word or a move")
at the numerous tower lights,(colon)
white, orange and blue, (semicolon)
offices or homes, I’ll never know, ("at the offices and homes I will never know, which depict modern solitude.")
a depiction of modern solitude.
But the flicker of these lights shows signs of life,
secret worlds, strange, and jittery too (remove "too" and then period)
and as small and powerless I am (remove "and" start new sentence. "small and powerless as I am)
facing the imminence of all happenings
like a voyeur I wonder, (Period after voyer (sic), remove "I wonder")
I envy these lives I am casually drawn to (I envy these live to which I am casually drawn.")
and how blissfully lone I feel ("I feel blissfully alone...")
facing the grandeur of my surroundings
in the dark comfortable night
where the silent treat leaves all dreams wandering
and takes me somewhere new. (this sentence starts 10 lines before and includes one comma.Do see anything wrong with that?)

This poem is composed of two very long run-on sentences. If you lack the grammatical and punctuation skills to write these correctly, then it is wiser to use shorter sentences. There are a number of problematic phrases like:

"like a voyeur I wonder"

There is nothing inherent in voyeurism that would cause a particular type of wondering.

"how blissfully lone I feel
facing the grandeur of my surroundings"

Why should the speaker feel blissful?

"at the numerous tower lights...the flicker of these lights shows signs of life"

How does that happen?

I can understand most of what you've said, but to do so I have to rewrite it in my head. The reader should not have to do this, it is disruptive to the poem and it is not the readers job. I would suggest putting each sentence in prose form and seeing if the sentence is grammatical, and has the correct punctuation before you line it out as poetry. You may also want to set it aside for awhile (at least several weeks), and return to it with fresh eyes to see if it makes sense. This is a common strategy of most writers, especially when starting out.
