It is good that you are trying out guidelines of individual volumes for your pre-drawings.
Your proportions are pretty good in your WIP, but there are a few areas that are just a little bit off. Some things I see in particular are that the shoulders are a little thin, the hands are too small, and the hips are too low.
To fix this, remember that each shoulder is as wide as the head; the hands (from the bottom of the palm to the tip of the middle finger) are at least the length of the face from chin to eyebrows; and on females, the hips start to fan out at or slightly above the navel. It is different between males and females because, in addition to having wider hips, females' hips are more bowl-shaped than males', so that they can support the weight of the uterus during the heavy months of pregnancy.
If the human body is 7 head lengths tall:
-There is one head length between the chin and nipples.
-There is one head length between the nipples and navel / elbows.
-There is one head length between the navel / elbows and the crotch / wrists.
-There is one head length from the crotch / wrists to the middle of the thigh.
-There is one head length from the middle of the thigh to the middle of the calf.
-There is one head length from the middle of the calf to the soles of the feet.
The 7-head measurement is good for drawing stylized people of average height (particularly females). However, many people also use an
8-head measurement, which I've found to be better suited for tall, medium-build males. Really skinny males look kinda stretched out at eight heads.
sweatdrop Once you get comfortable with proportions, feel free to experiment using them to accentuate character.
Les triplettes de Belleville did this particularly well.
