This is an excellent Photo. The background black is simple and pleasing to the eye and naturally does not take away from the main photograph of the bowl of flame. You've done a good job of capturing the various colours of whites/yellows/red of temperaturs of the flames, but the problem is I can't see the egg!
Other than that, I'm at a real loss to tell you in what way you could possibly improve this photograph.
Is there any way you could possibly show the egg and not have as much flame? I doubt it? Can I possibly see an egg to the right of the small flame? Is that it?
