Nice capture. When I read GIF's, I thought that you had saved images in the GIF (Graphics Interchange Format).
This is basically a very nice image and certainly shows Irish Dancers like they are in performance. You caught them in the air perfectly. I love the way their hair is flowing out with the leap!
I think that cropping the bottom of the image a tad to eliminate the triangular section of the stage - bottom image left might add to the image. I also think that brightening the dancers a bit and blurring the background would also help to separate the two foremost dancers from the background. Their legs, especially, are in shadow...
I don't know if this is an improvement but will be happy to take it off the site if you desire.
I think that if I were to work more on this image, I would experiment with desaturating the dancers in the background a bit...
