the purpose of this scrappy collage is for artist's reference of Alacrity's torso.
yes, she pushes the extremes of human parameters; but in fantasy or scifi worlds, Ala is not quite human (eg some hybrid of pixy, elf or alien)
Alacrity is supposed to be petite ~ small bewbs~! (well, normal is ok .. just not her most imposing feature), an elfin but muscly torso - shiny set of abs please~! of course when she is clothed that won't matter much, but if unclad that's one of her distinctive features. [Ala's muscles aren't big, they are just very defined. For those artists who don't like to draw women with abs, I'd prefer she be drawn clothed or from different angles.] Her limbs are not as powerfully developed, but still lean and ropy ~ Alacrity is built for speed & agility more than strength. Her hands and feet are tough and callused (but still a woman's hands) - she can kill with them, not to mention perform all those acrobatics she enjoys. *If I had to choose, I'd prefer a pixylike Ala than one who's capable of killing you with her bare hands .. of course a combination of both is ideal. [ie, Alacrity is meant to be ripped .. but trim & lithe, NOT bulky. Or you can just paint her well-covered]
At first glance, or from a distance, Alacrity might be taken for a dainty little girl. But on closer look, she more resembles the tiny ferocious predator she is.
*screenshots are of Alacrity in ArenaNet's GuildWars (nekky here, normally wears more clothing~!), though Alacrity's concept existed way before then ..
