Closer crop of the subject and I would think it would appear in 4wheeler magazines. Cropping closer would not effect the feeling of being outdoors. I know that I tend to try to include everything in a scene all the time, but something it makes the viewers eyes wander around the scene and doesn't give the impact that it deserves.
Some levels adjustment would help to bring out the contrast a bit more. The position of the camera in the shot is perfect. This helps to give a bigger feeling of the 4wd at work.
