How fun Rick! That's a super cool looking car.
My favorite image is #2 with the motion added and the guy holding on to his hat! That's a fun photo. I like your angles with #3 and 4.
#1 though doesn't work for me with the blur all around the whole image. If you are going to add blur, I think it would look a lot better if you blurred it to imitate Limited DOF. So the bottom of the image should be in focus to include the car, then the out of focus blur should start in a feathered manner. to where then the background is out of focus and the car stands out because it is sharp.
