Good photography! I esepecially like the 2nd one. The first one would have been great with some fill flash to fill in the dark shadows common this time of year. And the last one could have used a horizontal format, but the reflections, the truck lights on and the light background above the truck is great.
I'm not criticizing your photos, but rather critiquing them. Here's a tip; the bottom one could have really been cool if in the horizontal format and with the truck or at least most of it in the left half or 2/3s. When you have people walking, cars, trains, planes, etc moving, you want to give more room in front of the subject and less behind. In short, give them a place to go. And think in thirds, just like a tic-tac-toe board with 3 sections across and 3 down. Put most of the mass, subject, or light or dark area centered where the lines of the tic-tac-toe lines intersect. For example, on the top photo, the Dodge on the tail gate and the corner of the truck is in the lower left intersection and the truck is aimed toward the top right intersection. The trees are well lit but not washed out. What a shame you didn't have some fill flash to lighten the shadows, it would have been a superb photo.
On the second photo, note how the dark shadow of the fender is in the lower right intersection, the wave is in the lower left and Dodge and the sun are competing for the upper right. And don't worry about the lens reflections, that's very common when shooting into the sun. Some lenses are less affected. I know my Nikon lenses are much better than the cheaper Vivitar lens I sometimes use.
I'm certainly no expert in photography, but I have won several contests and taught a few photography classes. Having good structure and composition of your photos makes them more naturally pleasing to the eye. Often times people like a photo, but they can't explain why. Good composition and contrast is usually the reason why. And having well composed photos often makes the difference between people asking to see more or them sneaking off to get away. And there's just something good feeling when you see a good photo of your motorcycle, truck, etc. Oh yeah, and the wife and kids. Can't forget them, but if you can at least get them setting in the truck or washing it.....
