I was pleasantly surprised how this turned out for a snap shot - I'm slowly getting the hang of using RAW files and layer blending - lots to learn - good fun too
I think it would have been even better to focus more on the sky or the rocks as a subject, and so make the horizon lower or higher respectively. You've certainly got the DOF to do it.
For me that explosive sky does not work so well because the main area of attraction has little detail in it.
I took many variations - different rocks/ratios etc - but this was the only one that jumped out at me on the computer, so I went with it and broke the 2/3 rule this time
Milan, I might try a B/W - thanks for the suggestion
