The concept of the wet shots are cool but the reflections on them look a little iffy to me. It's a pretty neat job though, counting the fact that wet reflections, especially in motions are difficult as hell to capture and pull off. Same goes to the spray as well, like Nato said, kinds of draws attention away from the stock of the photo, but it's good that you tried, because the next time you do it again, it'll definitely improve.
However, I am totally in love with the transcammer set. Gorgeous showcase of the car.
