Building the image of your character

Circles, squares, and triangles.

You probably use them to make up your character.

If you saw big hero 6 (I didn't yet ;- then you'll know that bay-max (is that how you spell it?) is made up of circles.

Alright, if you are making a simple character, most likely you need to know what type of character you want and how to build them to give the impression you want.
