The Girl in the Mirror

[dukealien]

Dear china-girl, 
I met you in an alleyway 
when your despondency soaked the sheets,
salted the air.
The scent sprawled out like a painting  "Your" instead of "the" here?
“draw me like one of your french girls” opaque for those who didn't see "Titanic" (or the many parody pics)
except for the fact that I could see is "for the fact" needed?
the hills rolling down your body. ...and is "the" needed here?
At least cover yourself in sheets.
Disgusting;
I left and
never looked back.
You are the mirror I cracked Good use of "the" here, but could it be "a" instead?
when I showered
until my skin blistered
and the hair splintered from my scalp. is "the" needed?
I abandoned you.
But you were reborn
into my shadow.  "as" rather than "into," or do you really mean as a new part of that shadow?
Is this your revenge?
China-girl let go. comma or exclamation points here?  "China-girl!  Let go!"

Up front, must admit I only caught L6 being a reference from the quotation marks and had to look it up.  Is the title/motif also a reference to David Bowie's song?  At least your signature was in my inventory (from "Slaughterhouse-Five").

In addition/explanation to the suggestions above, you might consider placing all uses of "the" under suspicion.  It can almost always be replaced by a descriptive word, or nothing, unless it's truly unique - the one, the only in existence.

The mood is well established, with effective images.  I don't get the *exact* story or interpretation of each phrase, but the impression is strong.  Very expressive.
