This is how muscle women look. The thing that bothers me is when people draw Muscle women with big, floppy boobs. Those people obviously don't know that our boobs are made of fat, and therefor, wouldn't exist at all if a woman bulked up to this point without them being fake. (Even then, being fake, they wouldn't have any flex to them.)
Er- Yeah, I have drawn the mucle women with big boobs as well. While aware of breast composition and the effects of rigourous dieting and excersize on them, I am also enough of a boob-geek to just draw them anyway, throwing realism to the winds.
