Designed Shapes

So I think that there is only one kind of shape in cartooning- and that's a designed shape. Unfortunately it's really difficult to draw a designed shape, because drawing a shitty shape is so damn easy. What is a shitty shape?

It's basically any shape that's easy to draw. A square, a sphere, circle, rectangle, an amorphous blob, hairy psycholined nonsense.

So one must mold a sense of not making a drawing easy and too undesigned. One must practice a design shape sensibility, and become extremely sensitive about the difference.
There are a number or reasons why a design shape is so difficult to draw:

1. A design shape depends on all other design shapes.
2. A design shape has number of definite lines.
3. By "definite" lines- they are not wonky- they are either a straight, a C-curve, or an S-curve. But its extremely difficult to draw a "real" S-curve, and not a wonky S-curve, so for now I say only Cs or Is.
4. There's always some kind of offset- a design shape does not have parallel evenly length-ed lines, because even lengths and parallel lines make a shape INORGANIC.
5. THE MOST IMPORTANT THING- a design shape leads your eye to where you want it to go.

Because you have five difficult criteria to juggle in your head to make a design shape work- I'd say putting a straight versus a curve is never a fluke; yet drawing squares and spheres is- because easy shapes are part of a child's geometry, they're shapes everyone knows. Designing Straight vs. Curves is more like an analytic proof in some college level math class.
