In addition to what has been said, I particularly did not like the series of photos for the simple fact that you used a model car as your subject. Avid car fans such as myself do not like to see photos of car MODELS. We like to see the real deal. Also, try to take pictures of the whole car. It is quite unsightly and disappointing to see any part of it cut off. It's like slicing off a chuck of the Mona Lisa.
I shot another series keeping the comments I received in mind. Hopefully the lighting & DOP are better.
I also took photo of the whole car instead of 'cutting Mona Lisa'. Do take a look.
