I like the first one - clouds are cool + fisheye is cool = coolest of the photos. Sincerely, your wife
The 3rd one is my favorite. You don't see many sunset through a fisheye, plus I think that one has the best balance of sky color. The clear sky make for better color and the clouds to the left frame the right side of the shot nicely. I really like the the second one too, it is a really nice composition. I might look even better with a tighter crop, there is a lot of dark on the left and bottom sides of the picture.
