Some nice shots in those sets. I'll comment on the red Kia. The first one (6262) is nice, but could use a little cropping off the top, maybe half the distance between the horizon and the top. The second one (6264) is a nice panorama, but the car could be shifted a little more to the right, rather than in the center, that would be a little more appealing to the eye. On the third one (6268), nice focus but very off balance. With a car or a person or an animal, there should be more room in the direction the subject is facing, so in the case of this one, it would look more balanced if the car was on the right, facing into the middle of the shot, rather than on the left facing out of the frame. A lot of potential here. What camera are you using? Can you put a grid on the view to help compose the shots a little better?
