I like this design. Love the feet, with the opposable toe. I'm not really digging the tiny Tyrannosaurus Rex arms though. They just don't seem to have much purpose. I doubt she could reach her lips with that cigarette. But that's me being grossly over-critical. The overall presentation is brilliant. Good work!
The question you should really be asking is, what the heck is up with the side of here head? Oddly, that's the creepiest aspect, for me. I keep wondering if you can see into the side of her face through that hole. And maybe the gun likes to smoke the cigarette?
