Fantastic shapes! You used a great source of smoke and the composition is very good. I guess you also used the PS curves a lot (is that your title?). The colour transitions are therefore a bit harsh but it makes the shot interesting.
i knew there would be lots of images like this.. and probably one of them will win or at least be in the top 3... but i can't help feel that as good as they all are, this one included, its a bit predictable.. still a great shot though...
