Wait, how did this picture score so low? I absolutely loved this shot. The gravel makes for nice contrasting texture and I like the blur. Even the border is nice. I think people just glanced and thought it was unfocused and felt that it was more the car than the wheels. Sorry it didn't do better.
This is just a toy... the wheels are not very visible and they do not represent much in this shot where they're supposed to be the central point of the shot...
Soft focus? or blurred image confuses me (what is the point?). Low image quality (jaggies on the windshield line are really noticeable). Lack of direction to the wheel(s). My eyes are drawn to the number on the top of the truck rather than the wheels. Work on directing the eye of the viewer to the intended focus.
