I like #1, but I'd see if I could pull up the foreground trees to give more separation from the background and to emphasize the foreground subject in balance with the background.
You have a great shot to work with so you should be able to do a lot with it.
#3, the trees seem almost infrared in color, and washed out and maybe lacking in dynamic range to be able to do as much with it. If you can use layers to pop the sky (per above) while also adding depth and richness to the trees (what's lacking both in the original and also in the edit above) then it will be a great shot too.
