A nice piece. The rifle has a nice shape and cool design. The armor looks a little clunky but if that's what you were going for then you achieved it. Though, I wouldn't have known that was a female if it wasn't for the message at the top right. And looking at the face it looks like a robot but looking at the body I can tell it's a person wearing clothes with armor plated on. And the upper body looks like she can jet-pack maybe, or just that manga mech style of stylized cosmetic armor.
Overall a nice piece. And again, that rifle looks good.
