I like thinking of this pose like this (minus the blood). He just gets done killing shelly with the machete. Bend down and picks up the spear gun (new toy for Jason) and then he hears the girl in the lake calling to shelly and he turns towards the sound.... This is the exact moment of the statue.. He then puts down the Machete and puts on the mask.
Of course I can be from anything but that is what it reminds me of.
the problem with the pose for me
(Compared to the Kane pic)
the wrists are pointing down, Kane's wrists arent. Kane's wrists aren't bending.
The arms on the statue are too much behind Jason, the arms on Kane are to his sides, Jason's arms are going back like a child temper tantrum pose
(Jason's Shoulders are pointing down while Kane's shoulder's are not, Kane's pose is more manly, Jason's lower shoulders are almost feminine)
the head twist, Has Jason ever done a head tilt that exaggerated? it almost feels like a Michael Myers pose. Kane on the other pic has his head forward.
So even if they look the same, Jason is still doing this really weird super model pose. (it does not look like a manly pose. it just doesn't. the shoulders and the arms going back is really weird)
Is this nitpicking? maybe, but If I had this I couldn't stop noticing all these weird details. nitpicking or not it is a pretty odd pose.
Almost looks like if Jason was pushing his arms back while pushing his groin area forward in a humping motion lol. almost like a humping pose (Jason doing Yoga )
it kind of looks like if Jason's body is arched, Kane's body in the pic is completely straight.
