I like Laura's sculpt. I don't mind Laura being cheeky/sexy at all, MC illustrations of females almost always had something cheeky about them, even "vestals" were in a way.
Overall, the gender stereotypes were/are very strong in the setting, hence the exaggerated shoulder plates on armor too.
Human soldiers have a serious lot of muscle (that goes for both genders, but even more so for males), probably through a tad of genetic enhancements/implents and most women illustrations invariably had quite alot of "charms" so to say (another genetic alteration thing i would guess). This fits the fluff as well, because companies providing enhancements thrive on getting people convinced that they need them...not unlike today, actually.
