The picture itself isn't too bad. I really agree though that the subject should be offset, as I can't tell whether i should look in front of or behind him. The picture also seems to throw the title off, as the man is stepping in the "boiling river" and looks carefree, while I would expect him to be taking the utmost care to keep out of the water. In that sense, the picture doesn't seem to jump into the category "decisive moment" as it doesn't seem like the subject was caught in a climatic, decisive, or vuenerable moment. Good quality though, its a perfect vacation shot.
