I kind of like the gritty feel of this photograph. Not much I could suggest to make it a technically better shot. I might have tried cropping it a little closer to the rear with less of the front of the truck showing.
This, to me, is a rather uninteresting photo... I would have attempted to find something that was a little more 'high impact' for this challenge.. The color range here is quite flat. The underside of the truck trailer showing in the upper left corner is a little out of place as well...
