Shading - cars

The car I chose to draw is the Pontiac Grand Prix-Reborn. I picked this car because it's my dad's car so it was the first one that came to mind. When drawing it, I first started sketching the basic rectangle shape of the car, and drew lines alligning where the details would be. After that, I just looked at the original photo and sketched what I saw. After doing so, I shading in regions that best suit the car so it adds more depth of the photo rather than a plain outline of the car. Shading in different parts requires you to foreshadow the overall "look" to the car, and how realistic-looking you can make it to be. I shaded in the tires black because they are the darkest thing on the car, then the rest of it was shaded in gray in some areas creating depth. Finally, I added in the details to such areas as the headlights, inside the tire tracks, etc. This photo took a lot of shading and time to complete.
