How many heads do we need for drawing a correct human figure ?
The standard model of "fine art" figure drawings is found to fail in "several" cases (doomed!).
In practice, strict applications for head to body ratio rules are often a recipe for human figure drawing failure.
The aesthetic strategies do not keep many people awake at night, nor is it of immediate practical importance.
You get a sense that you're working as part of a community towards a common goal : there's a kind of excitement to that.
