what do you mean when you say pillow-shading each limb
I mean that by having each limb outlined as a rectangular shape with lighter area in the middle, you make them look like disjointed pieces put side by side.

Comparatively, artists making Commander Keen used outlines mostly on the *out*lines, and have the body flowing together well, with shadowed areas of the shirt matching shadowed areas of the jeans to convey a common 3D shape.
(PS: PM'ing people is unlikely to give you faster/better reply than asking your questions on the forum itself).
