nice colors
however, if your main subject is the car, you might want to shoot lower, so that the attention is placed on the truck itself and not the buildings or the scenery. when I look at the 1st photo I see a nice tall building with a yellow truck parked near the bottom, and I might think that the truck is an eye sore that ruins the nice building shot.
the 2nd shot is the same... i see the nice blue sky, then i see the trucks, and then i keep searching for the main subject and might end up looking at the mountains intead of the trucks.
it looks like you were shooting wide, so maybe you can try shooting closer to the trucks next time so they'll take up the majority of the frame, with the background, well, being the background and not overpowering your main subject - the trucks
nice paint job and rims on those 2 though.
