Abstraction of Shapes

I have been reading the Abstraction of Shapes in Characters from "Character design from Life Drawing" by Mike Mattesi. I have been looking at emotional ties with certain shapes...

Triangle: Athletic. Dynamism. Precariousness. Solidity. Dynamic. Force
Circle: Friendly, Soft, Safe.
Square: Strength. Solid.

I have also been looking at the law of thirds. "Our minds want to create symmetry and the irony is that this causes disinterest in art. Contrast creates interest."

"The law of thirds can also pertain to the dynamic shape of the triangle. The number three is a powerful number. In general, you want to stay away from even numbers because they have a tendency to create symmetry. The number one does also. Between the forceful triangle and the rules of thirds, you should be able to create dynamic designs if you so desire."

I have attempted to use these techniques on a new set of silhouettes. By creating a varied set of silhouettes using abstract and forceful shapes within the silhouette, I have tried to evoke certain emotions within the shapes of the characters.
