Andrew, if anything I would have lowered the exposure on the glass. It's compressed and hard to tell but i think you lost detail of the beautiful stained glass with the increased exposure. Also check your white balance.
I like that first pic.
Mine looked much better in the preview. The computer I'm using is so slow, it took about 15 minutes to process the picture and then I didn't feel like doing it again. Here's the low exposure pic for comparison.
As far as I'm concerned a Camaro counts as a sports car, and it was in the Midwest, so, how do you tell the year of a Camaro by the tail lights? I don't think I'll remember enough detail but at least I'll know in the future.
