#1 for me, the color in the sky is better in it. If you keep #2, I would crop down from the top to lose that bit of blue sky along the top. And #3 really rocks! Love the lightning in it too.
Wow, Awesome Work Fred! All are great, but 1 and 3 are my favorite! The colors in the first one are great, and the lightning in the 3 is the icing on the cake. Nice work.
I prefer the second one - it appears more about the rocks, which are fascinating to me, while first one is more about the sky. There is a clash of interest in the first one between the rocks and intensity of the light. In second one, the light is not as intense, more like giving an idea of a time and a place, while the rocks retain primary focus. The water looks more 'ethereal' in the second photos as well.
