There is a beautiful simplicity here. Your lines are wonderful, the way they draw the eye from your face around the image. My only quibble is that your right arm looks a little awkward.
I like the chiaroscuro effect of the light on your body, drawing attention to your face and your hip. While nude, the placement of your legs and the fact that your hair covers your breasts give a modesty to the image in a timeless way, almost like an Old-Master painting.
The look in your eyes is good as well, there is a sparkle there, but it's a bit enigmatic, as if to say we may see your body, but your thoughts are yours alone.
From a photographer's point of view, the shape in the background could have been centered better and the element in the lower right corner foreground is distracting, but again, this is on the photographer, not you.
