She
I love this, clean lines and all the colours work wonderfully =D
the only thing I would suggest is maybe darken the biohazard symbol on her stomach, its a little light and blends with the skin a little to well making kind of hard to see.
and the highlight with the outfit and the skin are the same, maybe make them a little difference from each other so her out fit doesn't look like its made of lime green shiny skin.
besides that very awesome!
