AURG Thank you so much for making this, there are WAY to many tutorials with those.... weird blocky, bulky bodies, it's so hart to find a basic yet very well executed. Great job on the legs as well, I find them difficult to get a real understanding of to make them actually work right~ XD
Well, i don't go to any academy or school of art's, but i use the same method that is used in school ( i think ). 1) Copy real person. Though you have a manga or comic style, you MUST copy and learn the real body, and then you can deformed the body for make your style. 2) Lear to use a " toy box". Toy box, is really important for remind to you the difference of male and female's body. It is also useful for position and other things.
I don't search a photo and try to draw the people, but i looking from books and internet guides the muscles, bones and positions. I have invented the positions in this sketches, but photo can you help with difficult positions sometimes! For the head i like looking skulls and do portraits for learn nose, eyes and mouth!
Sorry for my bad english, i hope you have understood ^^''
