It's time to discuss the design differences between nu-Tifa and Stellar Blade Eve - the Black Haired Asian sex icons of the old and the new.

As you can see, Tifa lacks the muscle mass to justify her identity as a supposed trained martial artist.
Notice the underdeveloped thigh and leg muscles, both of which are active muscle groups in martial arts trainings. The upper limbs also lack visible trained improvement, the biceps and the triceps are subdued. The only noticeable part of her exposed body that shows exercise are her abdominal muscles and midsection. Save for Tifa's famous and iconic bust, there are minimal feminine curvatures in her design.
I have decided not to show her gluteus exterior muscle group - the point has been made.
Disappointingly, nu-Tifa is a pair of breasts on sticks.

On the other hand, Eve shows extensive muscle development on her limbs. Particularly, her thighs and legs are grown massively to match the activities of a battle angel and her frequent running. This also translates to a gratuitously impressive posterior, of which she is becoming well known for.
Upwards, Eve's arms also show muscle development on her biceps/triceps, and visible muscle lines to show she can actually lift all manner of heavy monsters, object, and machinery. Her abs are also well-defined. Her bust firm and plump. All of her features summarized into an alluring S-line curvature across her body.
Eve's buxom build is a feast for the eyes and I hope the new standard for female designs in the future.
