If I may, slight editing suggestion...
Not that you HAVE to stick with rule of thirds here, but where the picture is otherwise so easily lost, putting Johnny right at a crosspoint brings your eye right to him, which works really well here. The wiper blades also now help us get to the picture, which works well.
Also, cropping in... it's still VERY clear to us what the subject is because of the steering wheel and such and we keep just enough of the hood and the rusty roof to still bring us those elements and mood, but now we have a tighter focus and the oddly locked steering wheel on the rusty hulk becomes more noticable and lends more to the image.
Finally, sharpening and contrast (via curves adjustment) to just make it pop... just a LITTLE too much and totally on purpose, but it really gives you that "yeesh! drama!" look which I think works well given how much drama is implied by that picture. Also drops out some of the not so useful stuff in the cab and makes the picture and the wheel pop more.
