OK, after wasting my entire afternoon in photoshop (nevermind a looming deadline, thanks again blizzard ;)) I have a real guess. It's definitely a female figure standing with her right arm hanging down next to her torso (left side of pic), bent at the elbow. The elbow is the lowest bright spot. The middle bright spot is her high mid-riff, just above the belly button. Her left arm is pretty much completely in shadow, as is most of the figure.
All the stuff that people think is a sniper rifle etc. i think is just background. It could be buildings, or vehicles or god knows what, but it simply serves to frame the negative space of the figure.
I do think she's holding a gun though, as it looks like some kind of scope/flashlight on the right side of the pic, sort of in line with her bent arm.
30 more minutes and we'll see how much crack i'm smokin... aaaauuuggghhh can't wait any longer!!!
