I like this image very much. I like environment aspect of it, and I like the addition of the umbrella. I also like the balance between the bent leg and the umbrella, it just works.
The hot spots don't bother me, it seems natural.
One critique that might make it even better is all the sky on top doesn't do anything for me. You probably included it to make the person seem smaller in the environment, but the lack of details in the sky just make it a rather uninteresting element to me.
As for the theme, if I didn't know this was about dance, I would have thought this was about Yoga. The image doesn't scream dance to me but that's OK.
These are just one person's opinions. Hopefully they give you something to consider.
