So, I feel kind of ridiculous posting this here, but someone asked me today how, when drawing, characters can present themselves as more masculine or feminine. While I don't draw heavily anymore, this is the way I wound up explaining this basic technique to them, and thought it might be useful for
others to know (and how this works for male characters as well).
Now, I'm not just using Freeza and Cell for illustrative purposes because I love them, but because they're actually really good examples. Both characters express their presence by pushing their shoulders back, causing their chest to be pulled out. HOWEVER, if you look at Cell on the left, you'll notice his hips are pushed forward, which also shifts the pelvis forward. Whether it's intentional or not, most males walk this way (it's said because this shows off the "important parts" that represent masculinity, but that's still up for debate), mostly due to the fact on how men balance their body weight.
Freeza, on the other hand (right), has hips that are shifted back, which is how most women or feminine-oriented people walk, drawing less attention to that area, and thus a less masculine presence (which is why, when male-sexed, feminine-presenting characters "power up," their hips will shift forward, once again giving them a more "masculine" presence).
The rule of thumb here is that the back of the hips in a masculine character should form a relatively straight line from the shoulder to torso area, while the hips in a feminine character should form a very slight curve from the same area, almost like a parentheses (and this can be exaggerated or toned down to the artists' liking).
If you look in the mirror, this also creates (or diminishes) the roundness of the lower abdominal muscles (which gives women the effect of having slightly more rounded abdomens).
Hoped this helped! :D
