My friend is taking a poetry class and needs help critiquing this poem? can you give her feedback on it (good and bad feedback)

thanks!

Her eyes tell her story

But words don't leave her soul

Replaying images in her mind until she despises her reflection

she watches her devil escape thoughts

he rips out her soul allowing her to feel nothing but the sound of metal scraping on bare cold skin

He digs deeper

She begins to feel the unexplainable relief that one small object that keeps her living

the devil crawls back inside to her imagination leaving the rest of the world only to see the smile on her face that never lived.
