The reflections are good, however, I think the lighting is a bit messed up. Perhaps make the highlights and shadows a bit more noticeable. If you want to keep the bright refections, make the ground more reflective as it looks too matte.
That looks so right and wrong in the same time. (In a good way) The road and cars are actually very well done, as the previous post said, reflections a bit off. Otherwise, its all good, keep it up!
