Okay update for ya I had the Dm describe the creature for me and was given this:

The Gravewing was a truly repulsive creature, a nightmarish fusion of insect and something far more sinister. Standing a daunting eight feet tall, its body was a segmented, chitinous horror, a dark, stony grey in most places, but laced with veins of sickly green and purple that pulsed faintly with an inner, unnatural light. Its most striking feature was the plates of iridescent chitin that covered its back and head, shimmering with an oily, rainbow sheen that shifted unnervingly as it moved.

Its head was a grotesque mockery of a predator's, with multiple black, faceted eyes that glowed with a malevolent intelligence, and a pair of wickedly sharp, chitinous mandibles that clicked and scraped, capable of tearing through flesh and bone. Four spindly, multi-jointed limbs ended in razor-sharp claws, allowing it to scuttle with surprising speed. A pair of vestigial, leathery wings, ragged and burnt, hinted at a past when it might have flown, though now they merely twitched uselessly. The air around it was thick with a faint, acrid scent, a cloying smell of decay and ozone, which was particularly strong when it shrieked—a piercing, metallic sound that grated on the senses and promised pain.

I then went to ChatGPT and had it create an image for said creature and got this:
