I've looked at this image a few times, and quite frankly, I can't see anything I would change. Sure I can crop it seven ways to Sunday, but this is just a matter of taste and not necessarily making the image better. Because of the moving colour-casted clouds, the image has a surreal quality to be sure, and that is its chief characteristic, which is very nice. I don't see the new crop as any better and the first has more of an edge to it than simple focal point or centre of interest, which, IMO, is a formulaic way at looking at things.
