Knowledge helps anyone do whatever they want to do better.  As a professional artist, I studied
physionomy  and anatomy of the human body to get the proportions right.

One of things touched here is soundly based in physical fact.  The human brain, when mature, irrespective of IQ or belief, comes in one basic size.  That size is determined by the genetics of the human species.  The braincase (skull) may have some statistical varience to size, but for the great portion of human-kind, has one size for mature humans.

The size of a figure is determinable by comparison of the skull, versas the long-bone proportion distributions. A dwarf will have a standard head, and shorter long bones.  A basketball player will have the same size skull and longer long bones.

I got this info from school and talking with a Forensic Anthropologist.  She stated that it is impossible to tell height looking at a skull, but is vary probable to within a half inch to determine height from one long bone only, if age and sex are known.

Art is as much inspiration as it knowledge and how to use it..  The more you know, the more you can do with it! ^__^ V,,
