Insentient Sentinel - a poem by me

This is the final revision of a poem I wrote from the following prompt in my creative writing course at Coastal Carolina University.  Your comments/criticism are invited:

Write a poem, unrhymed, about a real object –one that exists in the physical world. As much as possible, limit yourself to concrete detail, physical description. In fact, try to include a sense (a sensory detail) at least every other line. Tryto make the object seeable, tactile, physical. As seen fit, bring in background to help characterize the object.

  

                        Insentient Sentinel

The street light's realm is shrouded in a saffron miasma.

A swath of opaque light carved from darkness.

A safe harbor from unseen fiends

That slither in the sinister shadows.

Luminosity filtered through the carcasses

Of generations of nocturnal fliers,

Doomed to photocell hell, Fused

to the frosted glass of a man-made moon.

Casting ethereal radiance on illicit transactions.

Thrown away women selling their soul.

The vacant gawp of crack head zombies

Fighting another battle in an undeclared war.

The lamppost bejeweled by the psychedelic remnants

Of a duct-taped flyer for a rave years past.

Partially obscured by a dog-eared wanted poster

For a lost puppy that no longer answers to Sparky.

Unable to either bear warning or witness

The jaundice-eyed Cyclops's

unblinking, sightless, oculus could

But afford a sanguine oasis.

A young girl bustling home after curfew.

Sharing Taylor Swift's heartbreak

Through awareness canceling headphones,

Oblivious to the footfalls of imminent danger.

Snatched from the blackness

Before she could reach the genial  

dartle of her neighborhood night light, only

A furlong from the sanctuary of home.

An amber alert bulletin, hastily affixed.

Hanging haphazardly, akimbo, hopeless,

Whispering in the gossamer wind. 

Covering the futile cold  case of Sparky.
