So how is the alleged cut on her shoulder is still flowing while the others are not? The alleged wounds on her arm just so happen to appear as blood streaks going in the same direction as all the other blood while she lays flat? 
You seem to be pinning a lot of hopes on the shoulder cut not being a cut. That mark was discovered long after anything previously discussed on here. All marks should viewed distinctly as well as being considered collectively or in tandem. Therefore, a cut on her shoulder that isn't a cut, does not impact on other marks actually being a cut. I hope this makes sense.
Re her wrist, if we look at your take on things, there needs to be a source for the runs that you see as gravitational in one direction. However, as can be seen by looking closely, there is no such source. You can see her skin, where you should see a blood source. You've got the runs the wrong way round.
