If this has been edited already, it could use some more tweaking for sure. Quite a few typos and some sentences really don't flow well, and the jumping from 1st and 3rd person so much(several times within the same act, with act 2).
And if this is truly it, story feels a bit incomplete. I know the main point of the story is the doll possession but it ends abruptly and the whole revenge plot went nowhere, as did the possibility of the doll being supernatural beforehand.
After seeing the other thread I'm not sure how much this guy is paying you or how specific with his ideas he was. It could be a decent if not wholly original story with a little tweaking though. The mood felt right for the 'horror scene' even it was kinda typical with the lightning strikes, lights going out, blood sacrifice sort of stuff.
