I’ve only ever learned to draw by imitating comic book artist’s rendition of things, mainly buff dudes. I never focused too much on females, but I still do study from the best. When you draw women, your lines have to be all that better more curves more sensual. Harder to do. You also have to make sure their faces don’t look masculine. At least when you draw men, you can clump on the muscles, much like sculpting, and make their faces as neanderthal as you want, and it’ll still be bad-ass. But with women, you have to take more care to make it look feminine. It’s harder.
