Dearest TYWD,
I fear this may be a slightly problematic interpretation of the assignment. While you have done a modification of the 40's screenplay it is not an original story. Part of the assignment is developing a feminine POV which you did well and the 40's film noire was quite believable.
however...

I do think you might have been better served by developing your own characters and plot. I realize you are not claiming credit for the story and are crediting the original work for your inspiration. This is all to the good but we are talking about creative writing here and I think you might want too consider a different story line.
Yours
Mad Lews
