You should maybe step back a couple of feet, the car does not have to be all over the picture. Also try a lower aperture figure, especially on the side shots, that makes the car stand out more. Good job on the reflections! Maybe it would have looked better with a brighter background for more contrast.
If you should see a man walking down a crowded street talking aloud to himself, don't run in the opposite direction, but run towards him, because he's a poet. You have nothing to fear from the poet - but the truth.
