Well I guess I'll be the odd one and say that I like the second one the most. The hellish reds and oranges are a bit abstract, but then you get a hint of the subject matter with the rooftop barely visible. The actual quality of the photo isn't spectacular, but I love the feel and the concept.
And as for the third one, I'm sorry, but I'm highly opposed to almost all HDRs I've seen, and this is no exception. It's a great shot, but the typical HDR haloing and the extreme contrast kind of wreck it for me. If your PP was a bit more subtle, then it would have been my pick too.
