I deeply like the imagery here. You have fantastic word choice and placement. I think this would make a great lyric sung to the song it was inspired by, you've captured the right emotions. My favorite part is the second to last stanza about the cool air chilling the spine and lingering over the bed where someone used to be. It's beautifully sad, how you've worded that.
The only constructive criticism would be to add punctuation between some of the lines for a bit more structure to read by.
But overall, excellent piece. I thoroughly enjoyed it, in a beautiful sorrowful mourning kind of way. Awesome.
