Huh. From that image, I thought it was just an open wound to her rib cage or abdomen, since it looks to me like her belt and lower torso continue below the damage, and that the white panels around the 2-1B's wrist are either uncolored or brightly highlighted sections of her skirt/tassets(? I don't know my pieces of armor). I could be totally wrong about all of that, though. If she does indeed have cybernetic lower limbs, they must be covered in synthskin, because her exposed feet and toe-claws are consistently colored the same as her hands and finger-claws.
