A well crafted photo. Good muscle definition. I think the pose is slightly awkward but does not detract.
I believe she could have been a bit more articulated in her position. For instance, her further back in the chair by a little and leaning further forward. Or the opposite. Sitting further forward and more erect.
She has such a nice body that there are many different angles to explore also.
Did you try it in black and white? In this case the color does nothing for the photo and the monochrome would definitely increase the dramatic effect.
Only minor comments. The photo is quite nice otherwise.
