well this quickly went off topic...
sorry but the first set do nothing for me, its a black car on a blown background, some of them the focus point seems to be on the ground rather than the car and some of them are just not interesting photos..
the 2nd/3rd set are better but still have alot of clutter in the background of the image you would be better having it againsed a blank wall than a set of stairs, my eyes are drawn into those instead of the subject...
