For the final step, I increased contrast and played with the color loevels, and also added a gradient to darken the back side of the car. I did this to lead the viewer's eye to the front part, which I want to pay more attention to.
The beauty of working in this way is that I could go on forever, or at any given time call it done and give it to the client. It's a matter of time. In this case, I decided to stop after 1 hour and work on other designs.
