Night sky:

[addy]

I enjoyed the read. There were quite a few parts I loved, mainly because I am a nerd and i loved seeing references to visual delay in the night sky due to the speed of light and relativity, and about terrestrial compositions being actually derived from stardust, the "if a tree falls in the forest..." philosophical idea about existence.

There are points where you get too telly ("telly" meaning that you explain things or spell them out, rather than using images that would instead evoke what you are trying to say. It's the difference between saying "I was sad and I cried", versus "my throat filled with seawater"). Once you spot those points, it's not at all difficult or intimidating to come up with imagery... in fact its one of the most creatively satisfying parts of writing a poem, and something that will make the poem uniquely your own if done right. I'll just point out a few of the instances below so you can work on it.

Flight of star shine holds my gaze
shimmering in a black back-drop, of velvet softness
myriad yet singular in awesome dynasty

ruling night heavens with majestic charm
lending passion, giving evocation to how does it arouse passion? How does it evoke? It would be more exciting to hear you describe it
soul and thoughts of man on tranquil nights

ever present light of distant pasts
guiding future with eternal illumination
as we, ponder self and unanswered questions here too, you can rephrase it so you don't spell it out for the reader

stars; essence of what we are
beauty of what we can achieve again this would be more interesting if you describe the idea instead
reflection of ourselves in the universal mirror

their brilliance, brought to life by our existence
in their brilliance
we shine with definition

Thanks for the read
