I think they are generally ok, but I did a check on number 7 and found it needed a little more tweaking. If you wish I will post a cropped version, and you can compare.
You did a great job on all of these. I used my 40d with a sigma 105 2.8 In Indianapolis about 5 years a go from the stands and got some amazing shots and thought how cool it would be to shoot from the floor. Did you get any first turn wrecks those are always neat with everyone all tangled up. I really like the first one shot up into the stadium lights. Great job!
i have some partial shot from the first turn but i you wanted a great shot from the hole shot you where stuck there for the rest of the race and where it was kind of sucked and you had to scarify all the best spots
