I doctored a few of your shots to enhance them considerably.
1) LOOK AT YOUR BACKGROUND. Do not compose the shot with stuff growing out of your truck.

2) If your camera has a histogram, use it to check your exposure. Every one of these was partially blown out on the exposures.

3) Investigate the rule of thirds and learn to implement it when composing your images.

Don't get all upset because I am pretty blunt with the criticism. If you were located anywhere near south Texas I would volunteer to meet up with you and shoot your truck correctly with professional camera and lenses and then process the images professionally for you.

If you send me your email I will send you the repaired pictures so you can do what you want to with them. Again, nothing personal inthe C & C here just to help you make better pictures in the future. And that truck definitely deserves professional-level photography.
