Part 3 of Computer rendering

 Let's continue what i have done last time.This time, i might skip some of steps but the skill is always same. I put black color on the area, that surrounds right side of wheels to make wheels a little convex.

 Then we reduce depth of black to see some lines of wheels.

 Filling the inside of wheels.

 Then we create another layer to paint the inside of wheels again, but this time, we only draw one side.

 The purpose of this step is to add shadow in some parts of wheel, that we can not see completely due to perspective.

 The rear is concave and the light comes from left, thus this part should be darker than other parts.

I use medium brush to cover the whole lights.

 

 Using hard eraser to rub out surplus red color.

 Modifying depth and extending some of red lines as rays.

 The reason i put orange color there is to bring a metallic effect to the body.

 Then we draw shadow at the bottom and cover other parts of body with orange color.

Notice that, the light is supposed to come from left, so it is necessary cover the front with few white color.
