I think you did a decent job. Don't worry about finding your own style, just edit them as you like and eventually your own style will come.
I've been doing cars for a couple years. I'm still not that good. I've been doing a lot of on-track stuff this year, but I'm actually editing a car show from Sunday now. I don't use Flickr a lot anymore, but I'll post a couple examples of mine.
These following 3 were from very busy shows. Literally about 70 people around that F40. Sometimes you just have to wait in position until people are out of frame, and jump while the iron's hot. I may have waiting 10 minutes crouching down for these shots. Usually if you wait there long enough, people will notice you and move so you can take a photo. There are some that are oblivious though.
These are probably a little dark, figured out my monitor was too bright not too long ago

Sometimes it can't be avoided, and you have to focus in on details. That's when the small aperture comes in. Though as has been mentioned in the thread, the correct aperture for the subject. That's one thing I don't think I get right.

Another option, and what I do lately, is to go either at the very beginning or very end of the shows. Honestly, with the heat and amount of people at shows lately I just don't go, or go early (morning shows) or late (night shows). I do hate waiting for people.

One thing I can pass on for sure, because it was told to me (on this site actually, yay for learning!), is not to crop too tight. It's sometimes very hard to do at shows. I crop much tighter than I would like to at shows. But, just be aware of it. Oh, and explore different angles.
