There are all kinds of things pointing off the picture.
For general picture making and composition, it's usually not a good idea to lead the eye off the canvas. Anything that resembles an arrow or point in shape, like the pointing finger etc leads the eye in that direction. An artist can exploit that awareness of leading the viewer's eye. So that's my main technical comment.
The figure looks very sculptural. The anatomy of someone with this level of muscle definition is begging to be done in black and white, though color works well too. But I think of Michelangelo's marble sculptures which are monochromatic. So it works well for me not being color. Good choice.
