1 has great colors but minimal elements to create interest. 2 is good, but I'd like to see more of the sunset and have her head less centered. I'd go with 3, but crop off most of the foreground--just below the light spots. There is no visible detail in it anyway. It puts more of the focus on that great sky! That is what I would do anyway. :)
