I can't believe I'm submitting... well, I won't call this a tutorial. It's actually just a collection of notes and things I sketched down, which I thought someone else might find helpful.
As you can see, I'm rather lacking when it comes to the male body, and could probably use a few tutorials myself.
Edit: Ok, rather belatedly I'd like to say thank you thank you thank you for the DD, and every single comment/fav!! It's amazing to read that this is actually helping people! Please keep in mind that this is meant only as inspiration- there are a million more body types than the handful I used this method to describe. Do the random combination exercise, reference real people, go out and make the world a beautiful and varied place
