a pretty good cell shading tutorial
too much work for eric
what i do is make a new layer
filter>find edges
then i change the contrast and brightness to the point to where there are a few black lines and a solid white background
delete the white background by selecting it with the magic wand tool
use the paint bucket tool to fill the body panels with solid colors, using "I" to use the eyedropper to select the color you are over, then releasing and clicking to fill the area with that color
then play around with the bucket some more and change the color of the whole image
here's an audi s4 i did
