I like the 3rd picture the best because the first 2 just like everyone else is saying have drawbacks because certain pieces that people notice are cut off. And knowing alot about cars is a plus here because certain things people are attracted to about the cars are missing atleast in cars like those...(Lame cars according to me but i wont be biased) The wheels possibly would be attractive and bring more balance to the shot. I dont like the background/setting that you chose for the scene. And i see a few things that arent meant to be in the shot as in they dont have a purpose. mainly the building and in the first pic i think the sunroof in the car is quite discracting from the portrait of the person because i think she is the centerpoint. Pictures otherwise have great quaulity and lighting in my books, good job.
Im a noobie to this forum but i like art and im just stating my opinion
