The use of the graffiti in the background helps give the observer an idea of the setting the picture was taken in. The aged wall with paint chipping and graffiti all over it implies that it is in an older, more run down neighborhood. Maybe implying that it is a part of town most people are scared to be in? The fact that the child is in fast motion also adds an element of fear, like he is running

The large black figure also adds quite a bit of fear to the photo. With pointed ears like a bat, and the way the figure is positioned, as if hovering over the child. The black figure is superimposed on to the photo, giving it more significance; if the artist purposely put it in there, then it must have important meaning.
I believe the artist is trying to make a statement regarding the pressures and fears of today's youth. The dark figure with drugs and alcohol that the child is running away from, but can't because it is his own shadow.
