Well done for being ready with your camera and capturing such a dramatic image on the spur of the moment. The apperture looks to be spot on with only a tiny amount of blur motion around the face area, but, the exposure for me is incredible, capturing just enough light to separate the man from the BG, adding even more dramatics to a great image. I would have liked to have seen the full flame in the picture, rather than leaving the frame, however under the circumstances this could be forgiven. I'll bet when it started to rain it dampened his 'spirits'.
