I guess i know what you mean but i think i have a different approch here.
At first i would say if the dead body could be obviously be seen it would not lay there for hours until soemone in the night found here and informed the police. I mean the dead person was brought to the garbage box to be unseen.
And at least it is not important that it is dead body , it could also be an explosive or whatever is seen on a crimescene.
The important things are more on the left of this scene. These two persons on in the lights of the car.
The rest is more to distract and give the eyes something to look at without being pointed to the obvious things. I mean the detectives were not there if there were not something around.
The dead victims legs has a strong contrast with the light on the wall without presenting instant what it is. I am pretty sure that it is more interesting to first grab the intention and in a closer look recognize what it is then showing it directly. I think this makes the scene more different and the time you need to watch and recognize is longer. At least this means itis more "interesting" and less boring.
But nevertheless you have good points
And if it would be a comic cover page you were absolutly right because a cover or movie poster needs more an instant eyecatcher. No one is searching for details on a Coverpage.
