I want a comprehensive book of anatomy for artists that shows how to draw everything, including women and men (and not just women as modified versions of men), overweight, underweight, ummuscular, young, old, people of many different races (and not just as special bonus chapters), every expression including chewing food, pulling your eyelid apart, sticking your tongue out, puffing up your cheeks, with folkloric and pseudoscientific facts about what it means to have a widows peak, various relative lengths of index and ring fingers, dimples, or those weird assymetrical teeth, and while we're at it this book should include orthodontic diagrams about problems with crooked teeth, as well as how to draw sexual organs of different shapes and sizes in various states of arousal (instead of leaving the crotchal area as a mysterious blank), wounds, scars, bruises, how to render skin that's freckled, sunburnt, peeling, acne-ridden, skin that has the imprints of elastic bands or wrinkled pillows, how to draw the results of bad and good plastic surgery, like nose implants and fake tits as opposed to real ones, also that weird drawing that shows how big your body parts are in relation to how much brainspace is dedicated to them, and a history of standards of perfect proportion for every culture, and a historical overview of the most popular cartoon-proportions over the past century or longer.

Not just healthy, brooding, white heroic muscle-men.

(I know that such a book would be huge and impossible, and at a certain point you just have to draw more from life. I'm just saying - such a book would be awesome.)
