in popular art, the "anime girl" has become the blueprint from which many artists worldwide derive inspiration from, redefining the canons of visual arts and more precisely of body proportions.
in ancient greece a man called lysippos redefined sculpture by setting new standards of body proportions (tiny heads, 8 heads figures).
this new set of standards which reshaped the world of sculpture in the ancient world is known as the cannon of lysippos.

every era of anime has it's distinct standards of body proportions or "style" (pic related).
now i have a question for the weebs; who are the key artists that redefined the standards of body proportions from each era?
