I find the #2 offers an excellent starting point for further processing. Not in the direction of #3 though - nothing wrong with the direction itself, just that #2 works very well in the "normal" mode just as well.
I like how the lone, drifting cloud in the far right balances the waterfall compositionally. It is quite a serene image, in spite of the storm in the background. Or perhaps because of it - the clearing of the storm heralds serenity?
