Just a rambling question

Cartoons are different, and I guess if you're used to looking at cartoon women who are "more attractive" than any actual woman can achieve (longer legs, bigger boobs, huge eyes, etc), then that looks good to you.
Plus cartoonists compete with each other, so if once having legs half again the length of the body was "beautiful", now they have to have legs twice the length of the body (like the above).

Human women, though, have legs that are only a little bit longer than the rest of their bodies:



Also

Notice the length of the arms compared to the legs. Your figure's arms are half the length of her legs.


I'm not saying you should draw a fantasy figure with a normal human's proportions, but you should try not to exceed a human supermodel's proportions.
That's my taste, though, and I may well be a raving feminist more concerned with women's self-image when they compare themselves to "idealized" drawings, than with young men's enjoyment of said drawings.
