No-I like this-the title is pretty much perfect for this "random shadow" hence the word Random-
"random shadow... howl from your house. I bleed through the night. I ache for your ghost"
I don't think you need anything to fix this...it's actually perfect the way it is...if you look at it the ending pairs up with the ending in the sense that it is random-but still feels like it's of the samething.
Random shadow...I ache for your ghost...shadow to ghost-what more do you need. I bleed through the night still seems as if it feets the situation b/c they all relate to darkness-I don't know, I guess.
But I like the poem and if you're satisfied with it then what's it matter if anyone says otherwise...good job
