It's a good exposure, but the the composition lacks impact. Maybe a vetical shot with more sky and move in closer to the truck might work. There is a good shot to be had there, you should go back and explore it more with different lenses and taking angles and maybe even different filters.
Cropped because of the background, which was horrible. Vertical was a definite no no. Shot others of the truck for detail but had only one lens, a 50 and there is just so much one can do with a 50mm.
