I say make it more graphic. Dead girl with pantyhose around her neck and blue lips.
Live girl in a skirt/dress with pantyhose, displaying gun. Make the gun a bit more obvious, maybe with the business end pointed into the camera.
I must say, though, you do damn fine work, Oleg.
If you get a chance here's my vision:
Scene, playground. In the background, a child is on some equipment. Guy is trying to drag the child off the equipment, child holding on for dear life.
In the foreground on one side of the photo, show the hip of a person beginning to draw from concealment.
