Some people in DA and in my real life asked to me about my cartoon and how I can draw they perfectly. Well this is an old tutorial that I learned in my school, is the classic "Circles and line" If use geometric figures is will be more easy to draw.
I also recommended that you see your body parts and look Anatomy
(that's why my characters have long legs and have the hips a little bigger because I'm a little slender
Well I hope this will be helpful for you
