Step 7 Ground Plane
Select the area just in front of the car and fill that in with black then reduce the opacity until you get a second shadow falling.
Step 8 Gradients
Use the magic wand to select the lower part of the car from the shoulder-line downwards.
Select the brush tool and select soft round pressure size. Make the colour black and change the flow to about 5.
With the area selected stroke a gradient as shown. The more you stroke the darker it will get.
Step 9 Door Shape
Add a gradient to suggest that the door has some body section and an air intake just behind the door.
Step 10 Wing Mirror Shadow
Add a gradient for the shadow being cast by the wing mirror and just underneath the shoulder to illustrate the undercut in the door.
Step 11 Beltline Gradients
Add gradients in the beltline areas and hood to give it more shape.
Step 12 Ground Plane Shadow
Add a gradient to the bottom of the car.
Step 13 Blade Detail
Continue to add gradients with a combination of a layer mask so you can quickly add and subtract colour as required.
Step 14 Strip Light Reflections
Car design studios have strip lights in them to make it easy to read a cars design language. Imagine how the light would fall on the car if it was standing in line with them.
Step 15 Exhaust 1
Select the exhaust pipe housing and fill in the dark areas. Then select the exhaust pipe itself and stroke some horizontal paths along it to give it a chrome like appearance.
Step 16 Exhaust 2
Add some dark gradient to the lower inner edge of the exhaust.
Step 17 Exhaust 3
Select the outer-most boundary of the exhaust and expand the selection. Select inverse and add a gradient to the bottom right area to make it look like it slightly swollen for the exhaust.
Step 18 Exhaust 4
Finally add some some white to the exhaust to make it look more like chrome.
Step 19 Back Light 1
Fill in the whole light with a red colour.
Step 20 Back Light 2
Add a gradient from the left side fading into nothing on the right.
Step 21 Back Light 3
Create a new opacity mask on the layer with the gradient and scribble some lines as shown. This demonstrates a reflective nature of a light can.
Step 22 Back Light 4
Add a white gradient from the left to give it the appearance of light coming in from the left.
Step 23 Head Light 1
Select the outer frame of the light and add some gradient.
Step 24 Head Light 2
Select the inner area of the light and add some gradient to the top.
