The truck itself is fabulous and wonderfully contrasted against the foliage. The road right beside it is a wonderful setting - so near, yet so far for the truck. Nice enough HDR conversion - I would've cropped out the sky completely though - looks very unreal and distracting.
When processing a shot like this, be sure to carefully watch the sky. It seems like this was shot early morning or late evening, which can make the whole process a bit more difficult, but you'll definitely want a more natural sky to score higher.
Nice choice of subject and setting. Though I like it in colour I think this image could be great in black and white. That patch in the sky is slightly distracting. I imagine that's an effort to scrub away an overexposed sky but maybe a gradient would work better.
