Step 10: Darken in Eric Cartman's body by following the basic body shape, but draw a series of bulgy curves that spill over the shape to represent his fat. Using the vertical construction line as a guide, draw three small ovals that represent his coat buttons and a darker line to the side of the guide.
Step 11: Finish drawing Eric Cartman by darkening in his feet and drawing two wide arcs that extend outside the body shape a bit to represent the top of his shoes.
Step 12: That's it! You now have a nice sketch of Eric Cartman from South Park. You can stop at this quick drawing for a rough, sketchy look or go for a more finished look by continuing to the step below.
Step 13: For a more finished, inked look, carefully draw over the final sketch lines with a pen or marker. Wait for the ink to dry, and then get rid of every pencil mark with an eraser. You now have a finished inked drawing of South Park's Eric Cartman! You can stop here or go to the final step to complete your Cartman drawing.
Final Step: For a completely finished Eric Cartman drawing, you have to color it. You can use markers, color pencils or even crayons! Color Cartman's hat a light blue. The poof on top of it, the headband and his mittens are yellow. Color Cartman's face a peach color. If you don't have peach, improvise! Use orange without pressing down hard, use light pink or anything that looks right. Experiment. Cartman's shirt is red, his pants are brown and his shoes are black. That's it! You now have a completed drawing of Eric Cartman from South Park.
