All of the shots are framed nicely and for the most part, well composed. But on most of them, the focus seems to be a little off. In #1 and 2, the second and third cars were in focus, the the one in the lead was not. Maybe you intended that result, but it's distracting from to the overall shot. Also, they all have contrast issues. But, it's a great subject to shoot and it looks like you had fun and that's what really matters!
