not much of a clue for me.. still a great job

I also am too out of it to know who 'she' is, but nevertheless I find the mysterious simplicity and (kind of) threatening slash compelling. As for messaging, I think a more-succinct "She's BACK" would have greater effect.

I don't get the hard edge that curves through the background and text in the northwest quadrant and that isn't explained in the SBS. I personally just find it distracting.

The slash is not very scary. Stronger shadows and less-bright white might add drama. I also think the black border weakens the impact of the slash. Reconfiguring the '2' so it suffers more from the slash would be more disturbing.

If the thing sticking out of the bottom of the slash is supposed to be some sort of sword, then a steely, metallic finish would make it more recognizable. The eyes inside the slash are difficult to discern. Deleting them would focus attention on the sword. But one identifiable eye peeking out of the slash might add a level of creepiness.
