i actually think i like the lighting. because the window light is bright against her dark clothes, you have to concentrate more on her silhouette and each move instead of her muscle definition.

As with many people who are afraid to show off their bodies, she's wearing black, so we can't see the details of her moves. Also, the lighting is bad; the backlight from the window obscures her. I recommend whoever is taping this use additional lights to make it easier to see HER.
