This image has an excellent point of view but I agree with a previous commenter - crop more of the image. Often, in pictures, less is more - let the viewer fill in all the other details - we don't need the rest of the truck to know what it is. In this challenge, I gave you a 6 - it was a well taken image.
In my opinion the image suffers from being oversaturated. Also the composition is bright in the upper right and dark shadows in the lower left. Needs some balance in that regard. Try cropping out from the turnsignal up and mid bumper down (landscape).
I think the building behind the truck detracts from the composition, but mostly I think you probably suffered from rusted car overload. DPC sees way too many, especially in challenges where it's just much too easy to throw one in.
Out of the hundreds and hundreds of rusty vehicles entered in this challenge yours might just be one of the best. Although I would have darkened the lighter part of the building near the top because it sticks out a little to much. Good job.
