I’m still fooling around (worked on her face mostly so far), but here’s one thought I had about an outfit.
The thinking behind this is based on the fact that Samara compares her role as a Justicar with that of a knight-errant. Also, unless I’m terribly wrong, she has no possessions. From such a roving, deprived lifestyle - and being quite old for an asari, I feel her appearance should be at least somewhat worn.
As for the outfit, it should be something practical - e.g. suited for combat. Since the devs went for the claim that her abyssal cleavage was okay because she relied on barriers, I’m not going for armour, either.
A tighter top might be more comfortable, though.
I usually love my first rough sketches, and if I’m lucky, the finished result will be decent, too. But I hate these intermediate stages with a passion.
