Tonally it was a bit muddled I thought. It played out like a horror/thriller (supported by the score) but ended on a gag punchline. I felt like you should have gone one way or the other - either concentrated on the comedy or the drama. As it is you have a thriller setup that doesn't quite work (why exactly is she so blase about waking up with a missing finger?) and a comedy resolution that comes completely out of left field. That all said, it was a decent job in terms of direction, so you should definitely keep at it.
