Nice set Steve. Nice and sharp.
There are a couple of things that in my opinion can make them better. I think the crop is far to tight on most of them, the top image looks very odd in hue, pinkish/blue. What was your white balance. Auto can do this. I always try to set my white balance to the conditions or do a custom white balance.
I still like them very much. Would have liked to have gone myself but Le Mans was on the tele.
