Why is an ISD captain posing like that? Maybe she had an accident and had to by cyborged and that explains the need to stand like that. Or we need to be reminded she has a booty and curves.
She's not an ISD captain in that picture. She's an Imperial pilot leaning against her ship. The perspective on her arm and the wing is jacked up but overall I don't think it's that different from similar drawings of male pilots in relaxed poses next to their ships..
