Great shots Todd, I really like them all!
Here are some of my (insignificant) thoughts:
Photo 1: Technically fantastic I think, but I'm not sure if the background is interesting enough for that shot. Had the sky had some interesting clouds it would definitely be an incredible image.
Photo 2: Fantastic. I love everything about it, honestly.
Photo 3: I think the photo is dynamic enough that you pulled it off, but it could definitely benefit from a more interesting sky.
Photo 4: This one I do really like, though I think it's a little extreme for most of the foreground to be the gravel trap. If you could somehow fit a crowd in instead I think it would really help with that.
Photo 5: Awesome, especially how there are cars running the length of the straight.
Photo 6: Same as above except more dynamic, which really makes it stand out! The winding track leads your eyes through the image.
Photo 7: Beautiful. Shows the wonderful scenery very well, and I love the Porsche centered between the trees.
Most of the things I said could have been improved were things out of your control, and considering what you were working with you did a stellar job! You're at a completely different level than me when it comes to photography, so my comments feel really out of place. :P
