This should do well...with the right balance and composition for the challenge, and has enough other great photographic elements to make it work allround.
I don't know what to do with a great shot like this that misses the topic. These topics are silly sometimes but since it says "RULE of the thirds" I suppose we have to comply. This works for the fifths but misses the thirds. Still a good shot with just a bit of halo at the horizon.
