Awesome piece. Mind you, while I do adore the style and brilliant gaze paired with a rather peculiar gaze in her eyes, I find there's an issue with her anatomically speaking. From the way she stands her curvature is simply incorrect. At the mid-riff, where her abdomen starts up until her breasts, it's like there's an additional few inches that somehow make up for the angle her ass and hip indent portray. This obviously doesn't make much sense. Something I would consider taking another look at.
Otherwise, this is rather fantastic. Keep at it,
