When you design the most important part of your design is the Silhouette.

The silhouette should be:
1. Simple Iconic and memorable: Be appealing.
2. Communicate: Define the emotional tone of your character (even if the interior details and color are blacked out).



1.Simple/Iconic/Memorable/Appealing:


To complex and forgettable.




To simple and forgettable.


Just right ;)



(I believe Bill Perkins is responsible for this famous sheet. )



2. Communicate clearly:


There three basic emotional tones any piece of illustration or design will emote. Feelings of: 

Stability, Rest, or Movement.







Squares tend to emit a feeling of STABILITY.




Circles tend to emit a feeling of REST.



Triangles tend to emit a feeling of MOVEMENT.
