I like this photo! I like the movement blur that really helps sell this as a dance photo. It's interesting for me to look at because it's a culture different from my own. The low angle really works to add drama to the shot.
What hurts the image in my opinion are two things. 1) As someone mentioned, the dancers face has lost some contrast and color due to the backlight. 2) I find the person sitting on the right to be a distracting element, particularly the way he is cropped. I think you could have easily cropped him out without negatively affecting the image.
Hopefully these comments will give you something to consider.
