I think what makes this shot the most interesting is the juxtaposition between the light elements and the dark ones and the splashes of color. This was also an excellent example of when grain "works' in a picture.
For me, personally, this shot isn't real "moving." I tend to think that they appear flat and lack a distinctive purpose or subject. THAT said, the more I look at this, it starts to be more appealing. The colors really stand out, and it whispers, ever so quietly, "I have a story, but you have to listen carefully to hear it."
Nice abstraction! I like the tension of the tow main elements in this image, the graffitied metal wall and the scraggly weeds. The grain helps lend a painterly quality--almost pointilism. There's a lot to interest the eye here.
