I like the composition. In my monitor there is a tiny halo around the female dancers right leg, but that is minor. The reflection in the floor looks great.
Beautiful and well executed photograph. I just find the clothing differences odd and distract from the image. I can not come up with a reason in mind as to why the girl is wearing proper shoes and a beautiful dress and the guy has no shoes and seems to be wearing spandex underwear and a tank top.
