I find that drawing the head always balances out the proportions of the figure as there is always a certain ratio of head height to body height. In regular anatomy, it tends to be 7-8 head for females and 8-10 heads for men and for manga and anime, it's 6-7 for women and 7-8 for men (this is teens btw). For my own series, Jim's Days, the proportions tend to be 1 is to four meaning that the over all height is 4x larger than the head itself, giving the head itself dominance in the final product
