The picture of the 7 races is rather off.
(I get it they've got a graphics generator that does whatever it does)
(and they probably weren't planning on messing with it)
The classic proportions for Dwarves and Halflings comes from LotR.
These look like % downsized in 3 dimensions equally, and that's wrong.
Gina Carano's character as portrayed in Deadpool "looks" very stocky.
She isn't in real life, but she does look athletically muscular.
She's 5'8" and currently listed as 143 pounds ; higher when not competing.
Dwarves are 1 foot shorter and 25+ pounds heavier.
Their proportions wouldn't / can't look anything like a normal human.
They look more like my avatar, and not like a willowy version of Angel Dust.
