Like the shot, echo the comments above. One additional thought:
The combination of black top and lighting hides the model's shape. It seems like she has a very nice figure, but there's no shading or highlights on her tank top to suggest her curves; her right arm is next to her body and masks any waistline/hips, and her hair is doing a nice job of minimizing her bust. I like how the pose starts on her lower half, promising a nice S shape, but it didn't finish on the top. Maybe adjust her right arm very slightly to create space and reveal her waist, and a bounce card low and angled up on her right side to give her torso/bust some dimension? You could change the color of her top and leave the lighting alone, and that would probably do the trick, but like the black on black.
