It is fantastic dance shot! These moments don't happen often, unless you carefully stage them. How you caught it...keep as a secret
But this is Spanish, and there is no "drama". There is in the shadow, but not that much in the dancer. I think emphasis of contrast, darkening of the shadow while keeping you in the spotlight would enhance the mood.
I tried just two things, desaturate and hike the contrast "up there", to make shadow sort of be in the shadow itself and pop the dancer, whether in color or BW (and like the result
The fan and its shadow looking apparently in opposite direction (upside down) look strange, but that's the way you keep the fan above your head.
Also, IMO greenish cast of the original background is kind of bland, I'd correct it to be gray.
Don't add backgrounds IMO. Pure dance.
