The Mist. Great movie. When they "sacrifice" the soldier. They stab him in the stomach and leave him outside in the mist with all the creatures (you'd have to see the movie) and he touches his stomach, get blood on his hands, then kind of touches the window (exactly like your picture, almost, but he leaves a hole hand print) and then the monster comes and eats him.
I think it's great that you'd made it a little more different than from other kind of pictures with bloody hands where others use the picture by showing the whole hand, as is the pressure up on the window, here at this picture, it is only the tip of the fingers. It is very beautiful.
