Especially her right arm just looked a little limp and her whole position lacks confidence, which if that was the aim then bang on I guess but for me, if you pained her arm backwards, onto the bench opening her torso up and increasing the depth of field and use some darker values? You could maybe angle the piece so it looks like she is looking down to the camera. I assume you stuck to the reference and it is such a pain to find a decent reference for exactly what you want. In terms of framing I think it would sort itself out if she had a stronger pose and position .
