>>108824030A few signifiers that should be obvious:
Hair style
Facial traits (facial shape and jawline, eye shape, angles, mouth size and format, proportions)
Lacking pomme d'Adam
Lower traps (doesn't need to lack muscle, just don't give her a roider neck if you're using bodybuilders as reference)
Since you are just drawing and not working on a real body: overdoing the traits I posted before, like breast size or hips to waist, which again, lets you give her bigger muscles without fucking up too much
Body fat proportion - this one can vary a lot it's up to taste, but women tend to carry a bit more body fat. I find that making burlier women with a bit more body fat or lither athletic women with low body fat works well, but that's just me.
Muscle insertions
Line angles
If anyone knows something I'm wrong about, I'd be glad to learn more so just shitpost at me
