I suddenly kicked myself in the rear and said: "Yo! I wanna do a tutorial!"
And my choice of topic... well... Honestly? It damn near causes me physical pain seeing how some beginning artist maim the human body without even meaning to. So I thought I might as well do my best to help them get better.
NOTE: This is very down to basics take on anatomy. Many artists insist on studying and mastering all the 200+ bones 500+ muscles of human body, but I'm not that kung-ho yet. This is how I do it.
