Wow, elegant indeed. I love how there is a clear line of where the flame starts - not something I've seen in a lot of shots. I think it helps add to the elegance, as well as the soft, almost silky feel of the flame.
There are just too many contextless, dismbodied flame shots in this challenge, and to be honest none of them are terribly interesting. This is much like the Fireworks challenge, where the photos that scored best actually placed them in some kind of context. This one is very flat and noisy.
