I gave this a three but the facial expressions and the posing pull me out of this. Granted I know this is obviously not someone really trying to kill another person but it feels a bit too staged to me.

I'd also just super quick remove that tiny little branch poking through on the upper left side. It's a little distracting with it being pretty bright in an otherwise dark area of the photo.

PS Love the costumes and the editing, very cool.
