I like this one most, she s got the right kind of spirit for heroine! And I definitely love the HAIR , but I would try to make some change with the parts that are more in distance for instance make them lighter to make the space more obvious. The pose is brilliant!
Beautiful eyes, man! Very cool idea, nice composition. Maybe it would be cooler (dont know, u have 2 try) to make stronger contrasts on the body: stronger shadows, stronger lights, make it more plastic. For example nice shining moments on the titties, the skull in the hair and some details on the cyber-hand.
She loox very exotic, as a cyber-pirate bimbo conquistadora.
