I love the blue tones to this one, but I think there are too many distracting elements in front of and around the cool looking smoke. I read an article on photography composition once that said the first rule of thumb is to always remove clutter. anything that's not important to the picture, if possible, get it out of the picture. But I really love the contrast of the colors and that beautiful blue.
