The quality of your work is really starting to take off. I love the simplicity of the first one - great motion blur and yet the car is nice and sharp. The tight crop works really well for me as well and, despite being averse to that tilted photo effect, I think it works really well here.
#3 is the weakest here. While the driver is sharp and the motion blur is good it's a little too tightly cropped which enhances the fact that we're looking at a small car with a large man in it so it throws the scale of the shot if that makes sense.
