Hi Mark
Welcome to the forums. You seem to have linked to thumbnails of your photos. You will also get a better response if you just post one or two shots and ask for C&C specifically.
For example...

I like this shot. It's well lit and well framed. I would have considered shooting from a slightly lower angle but that might have stopped you being able to see the glass bonnet quite as well. The shot might also benefit from a slightly tighter crop to exaggerate the size of the front of the car.
All in all though, it's well balanced and nicely shot.
