I like the last one best because it introduces a bit of warm color with the cool. I would personally exploit that more with a bit of saturation boost, but that's just me.
On overall composition, the horizon in the middle is a little off-putting. Seeing what's available in shot #3, I'd say include about 2/3rds foreground/below horizon and 1/3rd background/above horizon, just enough to include the top of the mountain and give it a little sky headroom.
And as long as I'm wishing, I wish there was something more in a foreground element, like a canoe or something. I really hate to say stuff like that, because I'd prefer to just judge the merits of the photo as presented, rather than try to invent a new one that wasn't shot, but that's what's crossing my mind on this when I look at it.
